10 Symptoms of Pheochromocytoma
Reviewed: Dr. Mera
Symptom #5: Tremors
Tremors refer to involuntary repetitive contractions and relaxation of muscles which causes twitching. It can involve the face, arms, head, trunk, and legs. Most tremors usually occur in the hands. Some of the conditions that can cause tremors are stroke, hyperthyroidism, Parkinson’s disease, chronic kidney disease, substance abuse, caffeine use, alcohol use, inadequate sleep, hypoglycemia, anxiety, and more.
In pheochromocytoma, the release of catecholamines causes the heart to pump faster, diaphoresis, and the blood pressure to rise. It also causes tremors.
