What causes palpitations and cold sweats?

Palpitations and cold sweats may result from conditions such as hypoglycemia, diabetes, myocardial ischemia, or arrhythmia. Once the underlying cause is accurately identified, targeted treatment can be initiated. A detailed analysis follows:

1. Hypoglycemia: Inadequate dietary intake of carbohydrates—or delayed gastrointestinal digestion and absorption—can lead to insufficient glucose supply, triggering hypoglycemia. This may manifest as palpitations, cold sweats, difficulty concentrating, and pallor. Management includes immediate consumption of high-sugar foods (e.g., candy, fruit juice) and, if necessary, intravenous glucose administration at a qualified medical facility.

2. Diabetes: Impaired insulin function may lead to diabetes, which can cause palpitations and cold sweats, along with classic symptoms including polyphagia (increased appetite), polyuria (frequent urination), and polydipsia (excessive thirst). Treatment typically involves insulin injections administered under medical supervision at a qualified healthcare facility to achieve optimal glycemic control.

3. Myocardial Ischemia: Coronary artery atherosclerosis may compromise blood flow to the myocardium, resulting in palpitations and cold sweats, often accompanied by chest tightness or chest pain. Patients should follow their physician’s instructions to take medications such as aspirin and atorvastatin calcium to alleviate symptoms and prevent progressive cardiac damage.

4. Arrhythmia: Conditions such as sinus tachycardia or paroxysmal supraventricular tachycardia may also cause palpitations and cold sweats, frequently associated with fatigue and palpitations. Under medical guidance, patients may be prescribed beta-blockers—including propranolol or metoprolol—to help relieve symptoms.
