While the reasons for sweating when eating is often linked to a medical condition, it can also have psychological reasons.

Gustatory hyperhidrosis is medical condition. It occurs when you excessively sweat after eating or when you simply think about or look at food. The sweating is typically localized to your face, forehead, head, and/or scalp.
Sometimes the cause of gustatory hyperhidrosis is unknown. However, in some cases, it can be a symptom of another medical condition like diabetes or Parkinson’s disease. It can also be a result of nerve damage that adversely affects sweat production or sweat signals.
Frey’s syndrome is a rare neurological condition. People with Frey’s syndrome experience sweating and facial flushing, usually on one side of the face, during or after meals.
Frey’s syndrome occurs when there is damage to the nerves around the parotid gland. The condition usually results from surgical procedures, trauma, infection, or other injuries in the area. When the nerves regenerate improperly, they connect to sweat glands instead of salivary glands. This leads to sweating and flushing in response to eating.
In general, sweating after you eat can be an early indication or symptom of diabetes. Diabetes is a chronic condition when your body is unable to control blood sugar or glucose. When your body produces too much insulin following a spike in blood sugar, it can cause hypoglycemia. This, in turn, can cause sweating.
In extreme cases, a spike in blood sugar can sometimes lead to diabetic neuropathy or loss of nerve function. About a third of patients with diabetic neuropathy experience hot flashes after eating.
To manage the condition of sweating after you eat, first consider your diet. If you find that certain foods or types of foods trigger your sweat, start by eliminating those from your diet. If you still have problems, you may want to talk to your doctor.
One way to manage this condition is to cut out foods that make you sweat. Different types of food may make you sweat for different reasons. People can also have intolerances or allergies to certain foods, which oftentimes induces sweating.
In general, avoid or consume in moderation, foods and beverages that are high in sugar, high in carbs, caffeinated, alcoholic, spicy, high in protein, and processed.
