Those with chronic anxiety often experience digestion problems - most commonly irritable bowel syndrome. Individuals with IBS - a disorder with abdominal pain, cramping, bloating, constipation and diarrhea - have a colon which is more sensitive to certain foods and stress.
5) Sugar cravings
When someone is stressed, their body uses much more energy than normal. This means that they often need to refuel quickly, and therefore crave sugary foods that converts to energy quickly. However, the sugar high is followed by a sugar low, and the cycle starts again.
6) Trouble sleeping
Insomnia and waking regularly during the night are common problems for people with anxiety. Worrying and constant thoughts prevent you from relaxing and you can't "switch-off". Mental health charity, Mind, advises to make your bedroom a calm space, notice what you eat and drink and try breathing techniques.
