Understanding Different Types of Smelly Discharge

Smelly discharge can occur in various parts of the body and often indicates an underlying health issue. While some discharge is normal and healthy, changes in color, odor, or consistency may signal a problem. Let’s explore the different types of discharge and their potential causes.

Vaginal Discharge

Healthy vaginal discharge is typically clear or white with a mild odor. However, certain changes may indicate an infection or other health concerns:

  • Increased quantity
  • Green or yellow coloration
  • Watery or foamy consistency
  • Cottage cheese-like texture
  • Strong fishy or egg-like odor

If you experience these changes, especially accompanied by blisters, sores, pain, or vaginal bleeding, it’s crucial to seek medical attention promptly.

Penile Discharge

Any fluid emanating from the penis that isn’t semen or urine may indicate an infection or other health issue. Penile discharge can vary in appearance and may be:

  • Colorless or cloudy
  • White, yellow, or green
  • Thick or watery
  • Similar to cottage cheese in consistency

Additional symptoms that may accompany penile discharge include frequent urination, pain or burning during urination, soreness at the tip of the penis, and pain in the testicles, anus, belly, or lower back.

Anal Discharge

Anal discharge refers to any substance other than stool that comes from the anus. This can include mucus, pus, or blood. Persistent or abnormal anal discharge should be evaluated by a healthcare professional.

Discharge from Wounds

Infected wounds may produce smelly discharge as a result of bacterial growth. This type of discharge often indicates the need for medical attention and proper wound care.

Common Causes of Smelly Discharge

Various factors can lead to smelly discharge in different areas of the body. Understanding these causes can help in identifying potential health issues and seeking appropriate treatment.

Sexually Transmitted Infections (STIs)

Several STIs can cause unusual and often smelly discharge from the genitals. These infections may require treatment with antibiotics or antiviral medications, depending on the causative agent.

Gonorrhea

Gonorrhea is a bacterial STI that can cause white, yellow, or green discharge from the penis in males. Females may experience increased vaginal discharge, though many remain asymptomatic. Other symptoms can include pain during urination, testicular pain, and abdominal discomfort.

Chlamydia

Another bacterial STI, chlamydia often produces no symptoms. However, when symptoms do occur, they may include unusual discharge with a strong odor, discomfort during urination or sex, and genital itching or irritation.

Genital Herpes

This viral STI can cause smelly discharge from the genitals, along with blisters and painful sores. Some individuals may also experience a burning sensation during urination.

Trichomoniasis

Caused by a single-celled parasite, trichomoniasis can lead to changes in vaginal discharge, itching, burning, and genital soreness. Males may experience penile discharge and irritation.

Non-STI Causes of Smelly Discharge

Not all cases of smelly discharge are related to sexually transmitted infections. Other potential causes include:

Smegma and Balanitis

Smegma is a natural lubricating substance that can accumulate on the penis, particularly under the foreskin. Without proper hygiene, it can harbor bacteria and fungi, leading to balanitis (inflammation of the penis head) and unpleasant odors.

Thrush

This common fungal infection, usually caused by an overgrowth of Candida albicans, can affect both males and females. It may lead to changes in discharge and cause itching and irritation in the genital area.

When to See a Doctor for Smelly Discharge

While some variations in bodily discharge are normal, certain signs warrant medical attention. You should consult a healthcare provider if you experience:

  • Persistent or strong-smelling discharge
  • Changes in color, consistency, or amount of discharge
  • Accompanying symptoms such as pain, itching, or burning
  • Fever or other signs of infection
  • Unusual bleeding or spotting
  • Discomfort during urination or sexual activity

Early diagnosis and treatment can prevent complications and reduce the risk of transmitting infections to sexual partners.

Diagnostic Procedures for Smelly Discharge

When you visit a healthcare provider for smelly discharge, they may perform several diagnostic procedures to determine the underlying cause:

Physical Examination

A thorough physical exam of the affected area can provide valuable information about the nature of the discharge and any visible signs of infection or inflammation.

Laboratory Tests

Various laboratory tests may be conducted to identify the cause of smelly discharge:

  • Microscopic examination of discharge samples
  • Cultures to identify bacterial or fungal growth
  • Polymerase chain reaction (PCR) tests for viral infections
  • Blood tests to check for systemic infections or underlying health conditions

Imaging Studies

In some cases, imaging studies such as ultrasounds or CT scans may be necessary to rule out structural abnormalities or complications.

Treatment Options for Smelly Discharge

The treatment for smelly discharge depends on its underlying cause. Here are some common approaches:

Antibiotics

Bacterial infections, including many STIs, are typically treated with antibiotics. The specific antibiotic and duration of treatment will depend on the causative organism and the severity of the infection.

Antifungal Medications

Fungal infections like thrush are often treated with antifungal medications, which may be prescribed as oral tablets, creams, or suppositories.

Antiviral Drugs

Viral infections such as genital herpes may be managed with antiviral medications to reduce symptoms and prevent outbreaks.

Topical Treatments

For conditions like balanitis, topical treatments such as antifungal creams, mild steroid ointments, or medicated washes may be recommended.

Lifestyle Changes and Home Care

In addition to medical treatments, certain lifestyle modifications can help manage and prevent smelly discharge:

  • Practicing good hygiene
  • Wearing breathable, cotton underwear
  • Avoiding douching or using scented products in the genital area
  • Maintaining a healthy diet and staying hydrated
  • Managing stress levels

Prevention Strategies for Smelly Discharge

While not all cases of smelly discharge can be prevented, there are steps you can take to reduce your risk:

Safe Sex Practices

Consistently using barrier methods such as condoms and dental dams can significantly reduce the risk of contracting STIs that may cause smelly discharge.

Regular STI Screening

Routine STI testing, especially if you have multiple sexual partners or engage in high-risk sexual behaviors, can help detect infections early, even before symptoms appear.

Proper Hygiene

Maintaining good genital hygiene, including daily washing with mild soap and water, can prevent the buildup of bacteria and reduce the risk of infections.

Balanced Diet and Hydration

A healthy diet rich in probiotics and adequate hydration can support your body’s natural defense mechanisms against infections.

Complications of Untreated Smelly Discharge

Ignoring smelly discharge or delaying treatment can lead to several complications:

Spread of Infection

Untreated infections can spread to other parts of the reproductive system, potentially causing more severe conditions such as pelvic inflammatory disease (PID) in females or epididymitis in males.

Fertility Issues

Some untreated infections, particularly those caused by STIs, can lead to long-term fertility problems in both males and females.

Increased Risk of HIV

The presence of untreated STIs can increase the risk of acquiring or transmitting HIV.

Pregnancy Complications

In pregnant individuals, untreated infections can lead to complications such as preterm labor, low birth weight, or transmission of the infection to the baby.

Emotional and Psychological Impact of Smelly Discharge

Experiencing smelly discharge can have significant emotional and psychological effects on individuals:

Anxiety and Stress

The presence of unusual discharge can cause anxiety about one’s health and the potential impact on relationships.

Self-esteem Issues

Smelly discharge may lead to feelings of embarrassment and lowered self-esteem, particularly in social or intimate situations.

Relationship Strain

The need to discuss potential STIs with partners can create tension and strain in relationships.

Seeking Support

It’s important to remember that many conditions causing smelly discharge are common and treatable. Seeking support from healthcare providers, counselors, or support groups can help manage the emotional aspects of dealing with these issues.

Understanding the various types, causes, and implications of smelly discharge is crucial for maintaining good sexual and reproductive health. By recognizing the signs that warrant medical attention and taking preventive measures, individuals can protect themselves and their partners from potential complications. Remember, early diagnosis and treatment are key to managing these conditions effectively and minimizing their impact on overall well-being.

Types, causes, and seeing a doctor

Share on PinterestDifferent parts of the body can produce smelly discharge, which often signals an infection.

Different parts of the body produce different kinds of discharge, including:

Vaginal discharge

Some vaginal discharge is normal and healthy, and it is there to protect the vagina. Healthy vaginal discharge is usually clear or white and does not have a strong odor.

Changes in the color, odor, or consistency of vaginal discharge can sometimes indicate a problem.

Some changes that may point to a health issue include:

  • an increased quantity of discharge
  • green or yellow discharge
  • watery or foamy discharge
  • discharge with the consistency of cottage cheese
  • discharge with a strong odor of fish or eggs

It is especially important to seek medical care if there are also blisters, sores, pain, or bleeding from the vagina.

Learn more about the different colors of vaginal discharge.

Penile discharge

Any fluid coming from the penis that is not semen or urine may be a sign of an infection or another health issue.

Discharge from the penis may be:

  • colorless or cloudy
  • white, yellow, or green
  • thick or watery
  • similar in consistency to cottage cheese

In some cases, penile discharge may occur with one or more of the following symptoms:

  • a frequent need to urinate
  • pain or a burning feeling when urinating
  • soreness in the tip of the penis
  • pain in the testicles, anus, belly, or lower back

Discharge from the anus

Any substance that comes from the anus besides stool is called anal discharge. Examples include mucus, pus, or blood.

Discharge from wounds

Wounds that have become infected with bacteria may produce smelly discharge.

Smelly sweat

The skin contains two types of sweat gland: eccrine and apocrine. The body has more eccrine glands, and their discharge does not smell.

Apocrine glands are located in the armpits and genital area. They produce a thicker fluid that reacts with bacteria on the skin to produce the typical body odor smell.

Below are some causes of smelly discharge in different areas of the body.

Sexually transmitted infections

Some sexually transmitted infections (STIs) produce unusual discharge from the genitals.

A doctor may prescribe antibiotics to treat STIs that are bacterial or parasitic and antiviral medications for STIs caused by viruses.

Some examples of STIs that can cause smelly discharge include:

Gonorrhea

Gonorrhea is a sexually transmitted bacterial infection.

Males with gonorrhea may notice white, yellow, or green discharge from the penis. Other possible symptoms include:

Most females with gonorrhea experience no symptoms, though they may notice increased vaginal discharge. If other symptoms do occur, they may include:

Chlamydia

Chlamydia is another sexually transmitted bacterial infection. The majority of chlamydia infections do not cause any symptoms.

Males who do develop symptoms may have:

  • discharge from the penis
  • a burning sensation when urinating
  • a burning feeling or itchiness around the opening of the penis

Females who develop chlamydia symptoms may have:

  • unusual vaginal discharge with a strong odor
  • discomfort when urinating or having sex
  • genital itching or irritation
  • abdominal pain
Genital herpes

Genital herpes is a type of sexually transmitted viral infection. Most people who acquire it develop no symptoms. If symptoms do occur, they may include:

  • smelly discharge from the genitals
  • blisters around the genitals, anus, or mouth that may burst and become painful sores
  • a burning sensation when urinating

Females with genital herpes may also experience bleeding between periods.

Trichomoniasis

Trichomoniasis is a type of parasitic STI. The parasite responsible is a single-celled microorganism called Trichomonas vaginalis. Around 70% of people with trichomoniasis develop no symptoms.

Males who do develop symptoms may experience:

  • discharge from the penis
  • itchiness or irritation inside the penis
  • a burning sensation following urination or ejaculation

Females with trichomoniasis may experience:

  • changes to vaginal discharge
  • itching, burning, or soreness of the genitals
  • redness of the skin on and around the genitals
  • discomfort during urination

Smegma and balanitis

Smegma is a naturally occurring substance that helps lubricate the skin of the penis. Without daily washing, smegma can build up on the foreskin and head of the penis, causing an unpleasant odor.

Also, smegma can harbor bacteria and fungi, resulting in an infection. This can cause inflammation of the head of the penis, which doctors call balanitis.

Depending on the exact cause of balanitis, some treatments include:

  • antibiotics
  • antifungal creams or ointments
  • a mild steroid cream or ointment

Thrush

Thrush is a common fungal infection. In most cases, it results from an overgrowth of the yeast Candida albicans. This yeast ordinarily lives harmlessly on and inside the body, but certain factors can cause it to multiply out of control.

Some people who develop thrush experience no symptoms. If symptoms do develop in females, they may include:

  • typically odorless vaginal discharge that resembles cottage cheese
  • vaginal itchiness and irritation
  • soreness and stinging during sex or urination

Possible symptoms of thrush in males include:

  • possibly smelly penile discharge that resembles cottage cheese
  • a tight foreskin, or one that is otherwise difficult to pull back
  • irritation, burning, and redness beneath the foreskin and around the head of the penis

A person can treat thrush using over-the-counter or prescription antifungal medication.

Bacterial vaginosis

Bacterial vaginosis (BV) is the most common vaginal condition among females of reproductive age. It results from an imbalance in the numbers of harmful and helpful bacteria in the vagina.

Females with BV may have unusual vaginal discharge, which may be white or gray and watery or frothy. The discharge can sometimes have an unpleasant, fishy odor.

Other possible symptoms of BV include:

  • vaginal irritation
  • itchiness of the skin around the vagina
  • a burning sensation when urinating

A doctor usually prescribes a course of antibiotics to treat BV.

Foreign object in the vagina

A forgotten tampon or another foreign object inside the vagina can produce a bad, rotting smell.

If the object is not fragile, and there are no other symptoms, a person can remove it themselves. Otherwise, a doctor should.

It is important to remove the object as soon as possible. Otherwise, toxic shock syndrome can develop. This involves bacteria releasing toxins into the body, and without prompt treatment, it can be fatal.

Anal fistula

Smelly discharge from the area of the anus may result from an anal fistula. This is a small channel that has formed between the end of the bowel and the skin near the anus.

Other possible symptoms of an anal fistula include:

  • constant throbbing pain in the anus
  • swelling or redness around the anus
  • stool that contains pus or blood
  • difficulty controlling bowel movements

Doctors usually recommend surgery to treat an anal fistula.

Trimethylaminuria

Trimethylaminuria is an inherited condition that produces an odor of rotting fish.

People with trimethylaminuria are unable to break down a strong-smelling compound called trimethylamine. As a result, the body releases trimethylamine in sweat, urine, genital discharge, and breath.

Although there is no cure, lifestyle modifications can help control the smell. A person may, for example, avoid certain foods that can increase fishy body odors, such as:

  • seafood and shellfish
  • liver and kidney
  • eggs
  • cow’s milk
  • beans
  • peanuts
  • supplements containing lecithin

Smegma is a naturally occurring substance that helps lubricate the skin of the penis. Without daily washing, smegma can build up on the foreskin and head of the penis, causing an unpleasant odor.

Also, smegma can harbor bacteria and fungi, resulting in an infection. This can cause inflammation of the head of the penis, which doctors call balanitis.

Depending on the exact cause of balanitis, some treatments include:

  • antibiotics
  • antifungal creams or ointments
  • a mild steroid cream or ointment

Thrush

Thrush is a common fungal infection. In most cases, it results from an overgrowth of the yeast Candida albicans. This yeast ordinarily lives harmlessly on and inside the body, but certain factors can cause it to multiply out of control.

Some people who develop thrush experience no symptoms. If symptoms do develop in females, they may include:

  • typically odorless vaginal discharge that resembles cottage cheese
  • vaginal itchiness and irritation
  • soreness and stinging during sex or urination

Possible symptoms of thrush in males include:

  • possibly smelly penile discharge that resembles cottage cheese
  • a tight foreskin, or one that is otherwise difficult to pull back
  • irritation, burning, and redness beneath the foreskin and around the head of the penis

A person can treat thrush using over-the-counter or prescription antifungal medication.

Bacterial vaginosis

Bacterial vaginosis (BV) is the most common vaginal condition among females of reproductive age. It results from an imbalance in the numbers of harmful and helpful bacteria in the vagina.

Females with BV may have unusual vaginal discharge, which may be white or gray and watery or frothy. The discharge can sometimes have an unpleasant, fishy odor.

Other possible symptoms of BV include:

  • vaginal irritation
  • itchiness of the skin around the vagina
  • a burning sensation when urinating

A doctor usually prescribes a course of antibiotics to treat BV.

Foreign object in the vagina

A forgotten tampon or another foreign object inside the vagina can produce a bad, rotting smell.

If the object is not fragile, and there are no other symptoms, a person can remove it themselves. Otherwise, a doctor should.

It is important to remove the object as soon as possible. Otherwise, toxic shock syndrome can develop. This involves bacteria releasing toxins into the body, and without prompt treatment, it can be fatal.

Anal fistula

Smelly discharge from the area of the anus may result from an anal fistula. This is a small channel that has formed between the end of the bowel and the skin near the anus.

Other possible symptoms of an anal fistula include:

  • constant throbbing pain in the anus
  • swelling or redness around the anus
  • stool that contains pus or blood
  • difficulty controlling bowel movements

Doctors usually recommend surgery to treat an anal fistula.

Trimethylaminuria

Trimethylaminuria is an inherited condition that produces an odor of rotting fish.

People with trimethylaminuria are unable to break down a strong-smelling compound called trimethylamine. As a result, the body releases trimethylamine in sweat, urine, genital discharge, and breath.

Although there is no cure, lifestyle modifications can help control the smell. A person may, for example, avoid certain foods that can increase fishy body odors, such as:

  • seafood and shellfish
  • liver and kidney
  • eggs
  • cow’s milk
  • beans
  • peanuts
  • supplements containing lecithin

What does discharge look like? | The vaginal microflora and STDs | STDs and vaginal discharges | What should you do if you notice an unusual discharge? | How to avoid STDs


As any woman knows first-hand, vaginal discharges are a pretty common occurrence. And, most of the time, a normal vaginal discharge is nothing to be alarmed about. For one, discharges help keep the vagina clean and free of harmful pathogens.

But maybe you’ve noticed something…different…about your vaginal discharge. Perhaps there’s an unusual odor—or the color of the discharge isn’t the translucent white or clear color that it normally is. Maybe you even have flu-like symptoms, painful urination, or vaginal itching. You don’t know if it’s a urinary tract infection, a yeast infection, or something else.

If that’s something you’re experiencing, it may be time to get tested for STDs (also known as sexually transmitted infections or STIs).

Here’s the reason why you might want to look into STD testing: a number of STDs can cause distinct changes in vaginal discharges—altering the color, scent, and more. That’s because several STDs can affect something called the “vaginal microflora.”

Several STDs can negatively affect something called the “vaginal microflora,” a community of good, helpful bacteria. This can result in a distinct vaginal discharge. Whether it’s a frothy discharge or a green, chunky discharge, it’ll probably be easy to see that your vaginal discharge isn’t what it’s typically like. In this guide, we’ll explain the difference between normal discharge and discharges caused by a sexually transmitted disease so you can take next steps if necessary—like testing and treatment.

What does discharge look like?

Vaginal discharge is the result of the cervix cleaning and maintaining itself to stay healthy. During this process, the cervix sheds vaginal cells, cervical mucus, and vaginal fluids which results in a white, opaque substance. Women who haven’t yet reached menopause typically experience discharge because it’s a natural part of the body’s functions.

What color is discharge and what is it supposed to look like?

The answer to that will vary from person-to-person, but most women have a white vaginal discharge. As soon as a women’s menstrual cycle ends, her discharge will be minimal. By the time of ovulation during her cycle, many will notice a stringy discharge and it may even begin to thicken.

However, it’s important to note that women on oral contraceptives may have a reduced amount of discharge, making it harder to identify what “normal” is for you. However, if you are experiencing a yellow, brown discharge or even an orange discharge color, it may mean you have a sexually transmitted infection. Gonorrhea, chlamydia, and trichomoniasis infections can all cause changes in a woman’s discharge. (Related: Chlamydia & Gonorrhea Test)

The vaginal microflora and STDs

You may have heard that the gut is full of friendly bacteria. The vagina, it turns out, is also inhabited by a community of good, helpful bacteria—a community known as the vaginal microflora. Scientists believe that some types of vaginal bacteria actually protect the health of your reproductive system.

These bacteria, it is thought, produce lactic acid—making the vagina a less hospitable place for germs. This, in turn, helps ward off infections of the reproductive system. However, despite this, infections can still occur.

Case in point: STDs.

Some STDs—though not all—can change the vagina’s microflora community by populating it with an army of hostile pathogens (“pathogen” simply refers to very tiny organisms, like bacteria or viruses, that cause disease). If that’s happened, then you might notice that your vagina’s discharges—which largely consist of vaginal bacteria—are a little different than usual. Maybe the color of the discharge is yellow or green. There could be an odd smell, too. These are all signs of an STD discharge.

These changes can cause orange vaginal discharge, chunky yellow discharge, and other abnormal discharges. A change in how your discharge smells—such as having a foul odor—is another sign your abnormal discharge might be due to an STD. So, if that’s what your discharges have been like lately, it could be because you’ve got an STD lurking in your vaginal microflora.

But abnormal vaginal discharges aren’t only associated with STDs. In fact, there are quite a number of possible reasons why your discharge might seem unusual—in terms of its color, scent, texture, or volume. That being said, though, you can look for clues in your discharge—clues which hint at the possibility of an STD.

So read on to find out more about STD symptoms and discharges—including what STD-related discharges look like—to help you decide if it’s time to get tested.

STDs and vaginal discharges

Only some STDs are known to noticeably affect vaginal discharges. There are 3 such STDs to be exact: trichomoniasis (or “trich”), chlamydia, and gonorrhea.

Let’s consider each of these STDs in turn—and the effects they can have on vaginal discharges.

Trichomoniasis and vaginal discharges

If you’ve recently been infected with trichomoniasis, then your discharge might be yellow-greenish in color—or, perhaps, just yellow. Your discharge could be frothy—or filled with tiny bubbles—and may have a distinct odor as well (which is often described as “fishy”). Additionally, you may experience a heavier discharge than normal—particularly as you near your menstrual cycle.

This picture changes a bit if you’re experiencing a chronic, long-term trich infection—in which case, you might see mucus mixed in with your discharge.

According to the CDC, approximately 70% of people infected with trichomoniasis do not show any symptoms. So you can still have trich even if you don’t have any abnormal discharges! Further, it’s impossible to diagnose trichomoniasis solely on the basis of external symptoms. Thus, if you suspect you have a trich infection, it’s a good idea to get tested for STDs—something you can now do with a convenient, at-home female STD test kit.

Chlamydia and vaginal discharge

Any woman who is sexually active can get a chlamydial infection. You’re especially at risk if your age falls between 20 and 24.

Chlamydia is one sneaky—but common—STD because it rarely comes with any obvious symptoms (in fact, up to 80% of women infected with chlamydia do not have STD symptoms, according to one study).

That’s not the only thing that makes chlamydia an insidious STD, either: left untreated, a chlamydial infection can seriously hurt a woman’s reproductive system—which can result in infertility—or cause an ectopic pregnancy (also known as an extrauterine pregnancy). Chlamydia in women can also result in pelvic inflammatory disease—leading to chronic pelvic pain.

The good news is that, once detected, chlamydia can be effectively treated. So, because chlamydia presents a real danger to a woman’s health—and because it is a curable bacterial infection—the CDC recommends that women under 25 get an annual screening for chlamydia.

Chlamydia infections do occasionally present with symptoms—like mucus- and pus-containing cervical discharges, which can come out as an abnormal vaginal discharge in some women. So, what does a chlamydia discharge look like? A chlamydia discharge is often yellow in color and has a strong odor. A symptom that frequently co-occurs with this discharge is painful urination that often has a burning sensation in the genital area.

Gonorrhea and vaginal discharges

Like chlamydia, gonorrhea doesn’t always make itself known with immediately obvious symptoms. And also like chlamydia, gonorrhea discharges are frequently filled with mucus and pus—and commonly has a cloudy appearance—and can range from white to yellow to green in color.

Another symptom you might experience if you have gonorrhea is vaginal bleeding—even when you’re not menstruating.

What should you do if you notice an unusual discharge?

If you are experiencing abnormal discharge and think it could be because of an STD, the best time to take action is now because of the long-term health consequences of untreated STDs. Talk with your healthcare provider and consider getting tested.


Regular STD testing is key: the CDC recommends that sexually active women under 25 get tested annually for chlamydia and gonorrhea.


You can test for STDs from the privacy of home with the Everlywell STD test kit—which includes a free phone consultation with a physician if you test positive for chlamydia, gonorrhea, and/or trichomoniasis.

How to avoid STDs

To aid STD prevention, make sure you and/or your partner always use protection (like a latex condom) during sexual intercourse. Regular STD testing is another key step to take: while this won’t directly prevent STDs, it will let you know your status so you can get treatment for a sexually transmitted infection before it harms your health.

Conclusion

If you notice an unusual vaginal discharge, consult with your healthcare provider so they can evaluate your signs and symptoms and provide an accurate diagnosis.

While particular STDs can lead to abnormal vaginal discharges, a reliable diagnosis requires the use of laboratory testing techniques. But that doesn’t mean you have to personally go to a lab!

Why? Because you can test for STDs from the privacy of home with the Everlywell STD female test kit—which includes a free phone consultation with a doctor if you test positive.

STD Symptoms | Know My Status

STD symptoms vary, some are obvious, some are hardly noticeable, and some STDs show no symptoms at all. This means the only way you can be totally sure of your status is to get tested. Most STDs are treatable or manageable, but not without professional help.

If a partner tells you that you may have an STD, or if you have noticed any of the symptoms below, you should see a doctor immediately.

HIV/AIDS

Most people with HIV don’t feel sick right after becoming infected. However, some people may notice flu-like symptoms within a few weeks of infection.

Because symptoms may not appear for years after infection, you can’t rely on them to know if you have HIV or not. The only sure way to know your HIV status is to get tested.

STDs

Bacterial Vaginosis

This is not an STD, but it is something that should be treated. It causes a smelly vaginal discharge that may resemble a “fishy” smell and may become stronger after sex. Some women may have a white or gray discharge. Many have no symptoms.

Chlamydia

An estimated 50 to 70 percent of women and 30 percent of men with chlamydia have no symptoms. If you do have symptoms, they may include:

Women
  • Bleeding between periods
  • Unusual discharge from the vagina
  • Itching or swelling of the vaginal area
  • Painful or frequent urination
  • Stomach or abdominal pains
  • Slight fever
Men
  • Discharge or drip from the penis
  • Painful or frequent urination
  • Itching and/or burning around the opening of the penis
  • Pain or swelling of the testicles
