What causes excessive sweating and muscle cramps in hands and feet, and what medication should be taken?

Excessive sweating accompanied by hand and foot cramps may be caused by electrolyte loss, overexertion, hypocalcemia, hypothyroidism, peripheral neuropathy, etc. Symptoms can be improved through nutritional supplementation, rest, and medication. If symptoms occur frequently or are accompanied by numbness or weakness, prompt medical attention is necessary.

1. Electrolyte Loss: Excessive sweating leads to the loss of electrolytes such as calcium, potassium, and magnesium through sweat, causing abnormal muscle excitability and resulting in cramps. It is recommended to drink light salt water or electrolyte beverages after sweating and consume foods rich in electrolytes, such as bananas and milk.

2. Overexertion: After prolonged physical activity or exercise, muscle fatigue and accumulation of metabolic byproducts, combined with increased sweating, can easily trigger hand and foot cramps. It is advised to arrange rest appropriately, avoid overexertion, and stretch muscles promptly after exercise.

3. Hypocalcemia: Insufficient calcium intake or malabsorption in the body leads to low blood calcium levels, increasing neuromuscular excitability and causing hand and foot cramps, often accompanied by limb numbness. Patients may take medications such as calcium carbonate D3 tablets, calcium gluconate oral solution, and vitamin D drops under medical guidance to alleviate symptoms.

4. Hypothyroidism: Inadequate secretion of thyroid hormones affects metabolism and calcium absorption, leading to muscle spasms and abnormal sweating, often accompanied by cold intolerance and fatigue. It is recommended to take medications such as levothyroxine sodium tablets, thyroid tablets, and calcium carbonate chewable tablets under a doctor's supervision to relieve discomfort.

5. Peripheral Neuropathy: Damage to peripheral nerves due to factors like diabetes or infection results in abnormal nerve conduction, triggering hand and foot cramps and abnormal sweating, commonly associated with reduced sensation in limbs. Patients may follow medical advice to use medications such as mecobalamin tablets, vitamin B1 tablets, and gabapentin capsules to improve symptoms.

For daily management, maintain a balanced diet rich in calcium, potassium, and vitamins, adhere to regular sleep patterns avoiding late nights, engage in moderate exercise to strengthen physical health, replenish fluids and electrolytes promptly after sweating, and keep limbs warm to reduce symptom occurrence.
