Hypothyroidism is a common condition that significantly affects the body’s vital functions. Dr. Rasha Farouk, specialist in internal medicine and therapeutic nutrition, explains that many patients suffer from its symptoms for long periods without realizing the cause, leading to delayed diagnosis and worsening health.
Hypothyroidism occurs when the thyroid gland doesn’t produce enough thyroxine hormone, resulting in slowed metabolism. This hormone is essential for regulating heart function, digestion, energy, and mood.
Autoimmune inflammation (such as Hashimoto’s disease)
After thyroid surgeries
Iodine deficiency
Certain medications (like lithium)
Genetic predisposition
Symptoms usually develop gradually and include:
Symptom | Explanation |
---|---|
Fatigue and exhaustion | Due to slowed metabolic activity |
Weight gain | Resulting from reduced calorie burning |
Cold extremities | Due to weak blood circulation |
Hair loss and dry skin | Caused by lack of hormone regulation in tissues |
Depression and mood swings | Because the hormone affects the nervous system |
Slowed heart rate | Due to cardiac function disruptions |
Constipation | From decreased digestive tract movement |
Dr. Rasha Farouk explains that the main reason is the similarity of hypothyroidism symptoms to other common conditions like depression or anemia, which leads to misdiagnosis or being overlooked as general fatigue.
Blood tests for TSH and T4 hormones
Clinical examination to assess symptoms
Thyroid ultrasound may also be used in some cases
The primary treatment is taking a daily dose of synthetic thyroxine (levothyroxine), as prescribed.
Dr. Rasha Farouk advises regular blood tests to monitor hormone levels and adjust dosage as needed, with strict adherence to the medication schedule.
