What are the signs and symptoms of hypothyroidism? How does an underactive thyroid affect the body’s temperature and other functions? Find concise answers to these questions.

Fatigue and Exhaustion

Fatigue is one of the most common symptoms of hypothyroidism. People with an underactive thyroid often report feeling so exhausted that they struggle to perform their daily activities. This tiredness persists regardless of how much sleep or rest they get.

Weight Gain and Changes in Body Composition

Thyroid hormones play a crucial role in regulating metabolism, weight, and body composition. Individuals with hypothyroidism may experience weight gain and an increase in body mass index (BMI), even in mild cases of the condition. They may also develop a puffy face and excess weight around the abdomen or other areas.

Muscle and Joint Issues

Hypothyroidism can affect the muscles and joints, leading to aches, pains, stiffness, swelling, tenderness, and weakness. Research also suggests a link between thyroid disorders and autoimmune conditions like rheumatoid arthritis, which cause painful joint inflammation.

Changes in Mental Functioning

Untreated hypothyroidism can impact the brain, leading to symptoms such as anxiety, depression, apathy, impaired memory, reduced attention and concentration, low mood, and slower thinking and speech. These cognitive and emotional changes occur because the brain requires adequate thyroid hormones to function properly.

Sensitivity to Cold

People with hypothyroidism often feel cold all the time, even in warm environments. This is because the underactive thyroid can slow down metabolism, leading to a drop in core body temperature. Individuals with low thyroid hormones may report having cold hands or feet, or feeling chilly throughout their body.

Digestive Problems

Hypothyroidism can slow down digestion, causing issues such as constipation. This is because thyroid hormones play a crucial role in regulating the movement and activity of the gut, stomach, small intestine, and colon.

Increased Cholesterol Levels

Thyroid hormones are essential for the liver’s ability to remove excess cholesterol from the body. With low thyroid hormone levels, the liver struggles to perform this function, leading to an increase in blood cholesterol levels. Up to 13% of individuals with high cholesterol also have an underactive thyroid.

Cardiovascular Effects

Hypothyroidism can affect the heart in various ways, including slowing the heart rate (bradycardia), causing changes in blood pressure, and leading to variations in heart rhythm. These cardiovascular effects can result in symptoms like weakness, dizziness, and breathing problems, and may even contribute to more serious complications if left untreated.

Hair Loss

Untreated hormone disorders, including thyroid problems, can contribute to hair loss. This is because thyroid hormones are essential for the growth and health of hair follicles. Hypothyroidism may cause hair loss from the scalp, eyebrows, legs, and other body parts.

Hypothyroidism, or an underactive thyroid, is a common condition where the thyroid gland produces insufficient hormones. This hormonal imbalance can lead to a wide range of signs and symptoms that impact various bodily functions. Understanding the 12 key signs of hypothyroidism is crucial for early detection and effective treatment of this condition.

The thyroid gland plays a vital role in regulating metabolism, energy use, and the functioning of many organs throughout the body. When thyroid hormone levels are too low, it can result in a cascade of physiological changes that manifest in various ways. From fatigue and weight gain to digestive issues and hair loss, the symptoms of hypothyroidism can significantly impact a person’s quality of life.

It’s important to note that the early stages of hypothyroidism may not always present with obvious symptoms. However, without proper treatment, the condition can progress and lead to severe complications, such as infertility and heart disease. Regular checkups and monitoring of thyroid function are essential for early detection and management of hypothyroidism.

If you suspect you may be experiencing symptoms of an underactive thyroid, it’s crucial to consult with a healthcare professional. They can perform the necessary diagnostic tests, such as a thyroid-stimulating hormone (TSH) test, and develop an appropriate treatment plan to restore your thyroid function and manage the associated symptoms.

Recognizing the 12 key signs of hypothyroidism and seeking timely medical attention can help prevent the condition from worsening and ensure a better overall quality of life. By understanding the impact of an underactive thyroid on the body, individuals can take proactive steps to monitor their health and seek the necessary care to maintain optimal thyroid function.
