Thyrotoxicosis is a condition in which the thyroid gland produces excessive amounts of thyroid hormones (T3 and T4), causing the body's metabolism to become overactive. Common symptoms include:
- Rapid heartbeat or palpitations
- Sudden weight loss or gain
- Fatigue
- Mood swings or irritability
- Difficulty sleeping
- Frequent bowel movements or diarrhea
Causes of Thyrotoxicosis
The condition may result from several causes, including:
- Graves’ disease, an autoimmune disorder
- Excessive intake of iodine-containing medications
- Consuming too much or too little iodine in the diet
- Thyroid nodules or tumors
Possible Complications
If left untreated, thyrotoxicosis can affect multiple body systems, such as:
- Heart: May lead to abnormal heart rhythms or heart failure
- Bones: Increased risk of osteoporosis and fragile bones
- Nervous system: Anxiety, nervousness, or depression
- Thyroid storm (severe crisis): High fever, jaundice, vomiting, shock, and potentially life-threatening complications
