Under stress, anxiety, or constant worry, your liver produces extra glucose, which is blood sugar, to give you a boost of energy. But your body has a limit until it can keep up with an extra glucose surge, which happens when you’re under chronic stress or anxiety.

Moreover, type 2 diabetes is among the things anxiety does to your body. Some studies have shown that dealing with chronic stress increases your risk of developing type 2 diabetes.

An increased heartbeat, the rush of hormones, and rapid breathing can also upset your digestive system. Also, anxiety can make you more likely to experience acid reflux or heartburn due to an increase in stomach acid.

There’s a common belief that stress causes ulcers, but this isn’t true. The ulcer is caused by a bacterium called H. Pylori, and while stress cannot be the culprit, it can make you more likely to develop the disease or cause existing ulcers to act up.

Other things anxiety does to your body include constipation and diarrhea. You can also experience vomiting, stomachaches, or nausea because of anxiety or stress.
