Stress is a natural part of day-to-day life, and so are fluctuations in the hormone associated with it, known as cortisol.

But online, influencers blame a range of health problems on cortisol, from bloating to acne and poor sleep. The truth is, though, high cortisol is almost certainly not the reason you’re experiencing these problems.

Excess levels of the hormone can certainly have health consequences — namely a medical condition called Cushing’s syndrome, which is rare. In fact, in order to determine whether your symptoms are due to high cortisol, you need to see a health care provider, Dr. Natalie Azar, rheumatologist and NBC News medical contributor, tells TODAY.com.

So, most people don’t need to take steps to manage their cortisol levels. But managing your stress levels can certainly be beneficial.
