Hypothyroidism is a common condition that occurs when the thyroid gland does not produce enough thyroid hormones necessary for the body.
These hormones play a key role in regulating metabolism, energy, body growth, and various bodily functions.
Dr. Rasha Farouk emphasizes that hypothyroidism can significantly affect quality of life if not diagnosed and treated promptly.
Hypothyroidism symptoms may appear gradually and include:
Persistent fatigue, even after adequate sleep.
Unexplained weight gain.
Feeling excessively cold compared to others.
Dry skin and hair, along with hair loss.
Slow heart rate.
Difficulty concentrating and memory problems.
Chronic constipation.
Depression and mood swings.
Dr. Rasha Farouk stresses the importance of noticing any of these symptoms, as they often serve as early indicators of hypothyroidism, especially in women over 40.
Common causes of hypothyroidism include:
Hashimoto’s Autoimmune Disease: The immune system attacks the thyroid gland, reducing hormone production.
Iodine Deficiency: Iodine is essential for hormone production, and its deficiency can lead to hypothyroidism.
Certain Medications: Such as lithium, some heart medications, and certain cancer drugs.
Surgery or Radiation Therapy on the Thyroid: Can lead to partial or complete loss of thyroid function.
Congenital or Genetic Causes: Some individuals are born with underactive thyroid glands.
Dr. Rasha Farouk explains that early diagnosis of the different causes of hypothyroidism helps prevent serious complications.
Diagnosis depends on:
Blood tests to measure Thyroxine (T4) and Thyroid Stimulating Hormone (TSH) levels.
Testing thyroid antibodies to identify autoimmune causes.
Sometimes imaging tests, such as ultrasound, if needed.
Dr. Rasha Farouk emphasizes the importance of regular check-ups, especially for pregnant women or those with a family history of thyroid disorders.
Treatment is usually managed through:
Hormone Replacement Therapy: Such as levothyroxine to compensate for low thyroid hormone levels.
Regular Monitoring: To adjust medication doses according to hormone levels and symptoms.
Lifestyle Modifications: Maintaining a healthy diet, regular exercise, and proper weight management.
Dr. Rasha Farouk confirms that continuous treatment and regular follow-ups ensure symptom control and greatly improve quality of life, preventing complications such as heart disease or thyroid enlargement.
If left untreated, hypothyroidism can lead to:
Cardiac Problems: Such as slow heart rate or heart failure.
Myxedema: Swelling of the skin and tissues.
Fertility Issues: Especially in women.
Myxedema Coma: A rare but very serious condition.
