Differential Diagnosis for Profuse Sweating
- Single Most Likely Diagnosis
- Hyperthyroidism: This condition is a common cause of excessive sweating due to the increased metabolic rate and heat production. It often presents with other symptoms such as weight loss, palpitations, and tremors.
- Other Likely Diagnoses
- Anxiety or Stress: Profuse sweating can be a physical manifestation of anxiety or stress, often accompanied by other symptoms like palpitations, tremors, and shortness of breath.
- Menopause: Hot flashes during menopause can cause sudden and intense episodes of sweating, typically accompanied by flushing and a rapid heartbeat.
- Infections (e.g., Tuberculosis, Endocarditis): Certain infections can cause night sweats, which are episodes of excessive sweating that occur at night.
- Medication Side Effects: Some medications, such as antidepressants, can cause excessive sweating as a side effect.
- Do Not Miss Diagnoses
- Pheochromocytoma: A rare tumor of the adrenal gland that can cause episodes of excessive sweating, hypertension, and tachycardia. Missing this diagnosis can be life-threatening.
- Hypoglycemia: Low blood sugar can cause sweating, shakiness, and confusion. It requires immediate treatment to prevent serious complications.
- Cardiac Conditions (e.g., Myocardial Infarction): In some cases, excessive sweating can be a symptom of a heart attack or other serious cardiac conditions.
- Rare Diagnoses
- Neurological Disorders (e.g., Autonomic Dysfunction): Certain neurological conditions can affect the autonomic nervous system, leading to abnormal sweating patterns.
- Lymphoma: Some types of lymphoma can cause night sweats, which are a symptom that can be easily overlooked.
- Carcinoid Syndrome: A rare condition caused by a neuroendocrine tumor that can produce excessive sweating, flushing, and diarrhea.
