1. Panic attacks :
Panic attacks occur for many reasons: stress, chronic fatigue, and even genetics. However, if you often experience panic symptoms such as increased heart rate, sweating, and sudden changes in blood pressure, this may indicate an adrenal tumor, also known as pheochromocytoma.
This tumor has symptoms similar to stress, which is why doctors usually examine people who claim to have had panic attacks. Do not be surprised if your psychologist recommends a complete examination. This is a good decision that may help identify more severe diseases at an early stage.
