Symptoms of Hyperthyroidism

Common Symptoms

Hyperthyroidism is a condition where the thyroid gland produces too much thyroid hormone, leading to an overactive metabolism. This can cause a range of symptoms. Here are some common symptoms of hyperthyroidism:

• Unintentional weight loss: Despite maintaining the same dietary intake, people with hyperthyroidism may experience weight loss.
• Palpitations: A fast, fluttering, or pounding heartbeat can occur due to the increased metabolism.
• Diarrhea or increased bowel movements: Hyperthyroidism can cause an increase in bowel movements.
• Intolerance to heat: People with hyperthyroidism may feel excessively hot and have difficulty tolerating heat.
• Excessive sweating: Increased perspiration is a common symptom of hyperthyroidism.
• Menstrual irregularities: Women with hyperthyroidism may experience changes in their menstrual cycle.
• Nervousness and tremors: Feeling nervous and having tremors, especially in the hands, are common symptoms of hyperthyroidism.
• Shortness of breath and fatigue: People with hyperthyroidism may feel short of breath and easily tired.
• Muscle weakness: Hyperthyroidism can cause weakness in the muscles.

Common Symptoms in More Severe Disease

As hyperthyroidism progresses, more severe symptoms may develop. Here are the symptoms of more severe or progressed hyperthyroidism:

• Rapid, irregular heartbeat: People with hyperthyroidism may experience a fast or irregular heartbeat. This can be accompanied by palpitations, which are sensations of a racing or pounding heart.
• Weight loss: Unexplained weight loss is a common symptom of hyperthyroidism. This can occur even if a person has a good appetite or is eating normally.
• Muscle weakness: Hyperthyroidism can cause muscle weakness, making it difficult to perform everyday tasks or exercise.
• Irritability or nervousness: People with hyperthyroidism may feel irritable, anxious, or excessively nervous. They may have difficulty concentrating or experience mood swings.
• Trouble sleeping: Hyperthyroidism can disrupt sleep patterns, leading to difficulty falling asleep or staying asleep throughout the night.
• Fatigue: Despite feeling restless and having trouble sleeping, people with hyperthyroidism often experience fatigue and low energy levels.
• Sweating: Excessive sweating, even in cool environments, is another symptom of hyperthyroidism.

Intensive hyperthyroid symptoms require immediate medical attention. Contact the healthcare provider or have someone take you to the emergency room for:

• Very rapid heart rate (140 beats per minute or higher) or feeling that your heartbeat has become irregular
• Feeling agitated or confused
• High fever
• Loss of consciousness
• Unusual level of shakiness, sweating, or muscle weakness
• Diarrhea that doesn’t go away or improve over a day
