Heathline details three ways in which people with diabetes may experience excess sweating: one in response to low blood sugar, one in relation to food, and one solely occurring at night. The first is such an established symptom that diabetics are warned to check for sweat as a marker that their blood sugar has started to fall to unacceptable levels; the nervous system's trigger for sweating is signaled by low blood sugar levels.

The second is rarer, and is called "gustatory sweating" because of its exclusive relationship with food; it's associated with serious diabetics who may have suffered nerve damage, happens exclusively around food, and is confined to the head and neck.

The third is the dreaded "night sweats," or nocturnal hyperhidrosis. And it's not purely related to diabetes; the National Health Service also ties night sweats to sleep apnea, infections or hormone problems, amongst other possibilities. But it's definitely an issue for diabetics, and tends to be a signal of low blood sugar due to the body's insulin regulation at night. If you're on certain meds, they may be at the root of your sweating mystery. There's a class of medications known as diaphoretics, meaning that they cause excessive sweating in some people and you may just be one of those lucky ones.

The International Hyperhydrosis Society has a comprehensive list of these drugs, and many aren't associated with sweating in popular thinking — which is why it's important to carefully check possible side effects in medication advice. The list includes some pain medications, blood pressure and cardiovascular drugs, chemotherapy, hormonal treatments, anything targeting the endocrine system, some antibiotics, and many more; check the list out to see if there's a culprit in your medicine cabinet.

A second reason for increased perspiration is to help cool the body. People who live with anxiety are therefore far more likely to sweat as a direct consequence of anxiety attacks, PTSD triggers ,and general anxiety.

If you feel your anxiety has become dangerous or is keeping you from fully engaging with life, counseling can definitely help. Dietz says. Unfortunately, there are no MedExpress centers in this area.
