Gastroenteritis: When the Stomach and Intestines Become Inflamed

Symptoms of Gastroenteritis

• Watery diarrhea
• Headache
• Fever
• Muscle cramps

When to Contact a Doctor for Gastroenteritis

Most cases of gastroenteritis are viral and resolve on their own. However, if a person shows signs of dehydration or the illness becomes severe, they should contact a healthcare professional. Severe symptoms may include irritability, diarrhea for more than 2 days, high fever, six or more bouts of diarrhea a day, severe pain in the stomach or rectum, black or bloody stools, stools with pus, sunken eyes, extreme thirst, and dark urine.

Pregnancy-Related Symptoms: Nausea, Headaches, and More

Drowsiness, fatigue, headaches – a therapist will help!

Many people, especially with the beginning of autumn, complain of fatigue, drowsiness, headaches and general weakness of the body. Often people do not go to the doctor with such symptoms, thinking that this is seasonal and will “go away on its own”. In fact, contacting a therapist will help identify the true causes of this condition and prescribe a set of procedures to improve the condition of the body. The price of a consultation with a therapist will be fully justified by cheerfulness, good health and joy of life.

What can cause fatigue and drowsiness?

There can be many reasons why people feel generally weak, from lack of vitamins to chronic fatigue syndrome.

What does a general practitioner do if a patient comes to him with such complaints?

• asks the patient about symptoms and general health;
• prescribes additional examinations – tests, blood pressure measurement, etc. ;
• , when symptoms of a serious illness are detected, refer to specialized specialists.

If a child has these symptoms, it is very important that he is examined by a pediatrician (children’s therapist) in a timely manner.

In need of urgent medical attention

There are cases when it is especially important to take urgent measures, up to calling an ambulance:

• if drowsiness and fatigue are accompanied by severe headache, loss of orientation in space, nausea and vomiting, scattered consciousness and other similar symptoms that may indicate brain damage – a stroke;
• if severe symptoms occur in pregnant women in the third trimester, as they may be associated with preeclampsia;
• if drowsiness and headache are accompanied by a sharp change in skin color, itching and blurred vision.

When not to worry

Often, fatigue and drowsiness are due to the fact that a person simply leads a wrong lifestyle: little and bad sleep, too much work, not enough time in the fresh air and poor nutrition.

If the symptoms are related to such factors, then our therapist in Pushkin (St. Petersburg) will advise you on how to adjust your daily routine and what to pay attention to.

Headache and nausea

Headache, or cephalalgia, is an unpleasant condition in itself. A person experiences discomfort, and in especially severe cases, loses his ability to work. However, sometimes not just a headache, but also nausea. Such an ailment cannot be ignored: it can indicate serious illnesses.

Causes of headache and nausea

Painful condition can be caused by:

• atherosclerotic changes,
• vascular dysfunction,
• nerve entrapment,
• intoxication.

Nausea and headache accompany many diseases – hypertension, migraine, osteochondrosis, intracranial hypertension, SARS, chronic fatigue syndrome. This condition occurs in early pregnancy, with head injuries. It can be a messenger of dangerous diseases – brain tumors, stroke, meningitis. Therefore, you can not leave such symptoms unattended or self-medicate.

Call an ambulance immediately if:

• speech is impaired;
• skewed face;
• the patient lost consciousness;
• developed a rash or spasms of the neck muscles.

However, even if the manifestations are less severe, be sure to visit our clinic. We will provide the necessary assistance, eliminate pain and discomfort.

What should I pay attention to?

The doctor at the Private Practice clinic will definitely ask you a number of questions:

• How does cephalgia manifest itself?
• How often does it occur?
• Is headache always accompanied by nausea?
• What additional symptoms are present?
• Does it get better after vomiting?
• Does cephalgia go away after daytime or nighttime sleep?

Be prepared to answer these questions – this will give the doctor valuable information. Describe the nature of the pain – pressing, dull, stabbing, throbbing, aching. Tell me where the unpleasant sensations are localized: temples, forehead, occiput, cranium.

If other symptoms are present, be sure to mention them to your doctor’s appointment – this will speed up the diagnosis. For example, abdominal pain, photophobia, pulsation in the eye area are characteristic of migraine, and swelling and palpitations are characteristic of hypertension.
