Sweating that occurs on the forehead, scalp, neck, and upper lip while eating, talking, or thinking about food is called gustatory sweating. For many people, sweating occurs due to eating hot and spicy food. For others, however, it happens frequently after eating any food. In the persons, where eating any food causes sweating, it is most likely due to nerve damage in or around the parotid gland, the gland in the cheek that produces saliva. When this occurs, it tends to happen on one side of the face and is known as Frey's syndrome. In some rare cases, people with diabetes mellitus may experience bilateral facial sweating during eating. Those people who sweat profusely after tasting, smelling, or talking about food may wish to see a doctor. A doctor can diagnose Frey's syndrome or another type of gustatory sweating by: noting the characteristic symptoms, taking a medical history and carrying out the minor iodine-starch test. There is often little that can be done to fix the damaged nerves. Surgical procedures are available to replace affected skin, but they are risky and not often advised. A doctor may prescribe medicines and topical creams that help block undesired activities of the nervous system. However, one medication that has proved quite successful to treat sweating associated with Frey's syndrome, is botulinum toxin type A (Botox). This is injected into the affected area to stop the sweating.
