Excessive sweating may be a defensive reaction under conditions of exposure to the body in intense heat or prolonged physical effort. But in most cases, abundant sweat is the manifestation of severe affections.
Excessive activation of suppurative glands and generalized sweating occur most frequently in neurological disorders (with hypothalamus lesions), endocrine diseases (especially in hyperthyroidism), excessive alcohol consumption, diabetes, gout, or acromegaly. The fact that neuro-endocrine imbalances are a cause of generalized hyperhidrosis explains why almost all women in the menopause have this problem.
Abundant sweating may suddenly occur in myocardial infarction, sudden increases in blood pressure, hypoglycemic coma in diabetics, in the event of septic shock. So-called cold sweats appear in the angina pectoral crisis, in renal colic, bile, but also nervous states, fear, and even fatigue. When sweating occurs only at night, it is caused by bronchitis, rheumatism, pulmonary TB or heart disease.
The main role of perspiration is to keep the body temperature at a constant level of 37 C – the mechanism being called thermoregulation. In the event of overheating, sweat glands receive from the brain the “command” to convert excess heat into water, which is then eliminated through the pores, in this way the body “escaping” and some of the toxins in the blood. There are people who can suffer the inconvenience of excessive sweating in their professional lives: trade workers, hairdressers, electricians, musicians, nurses, surgeons, politicians, photographers, etc. 4% of subjects are affected at the same time by what is called erentobolia, that is, the flushing of the face.
Bacteria, guilty of unpleasant smell
Originally, perspiration, also called hyperhidrosis, does not smell (in fact, its smell is vague, uncomfortable). Unpleasant smell occurs when sweat comes in contact with bacteria on the skin surface. His appearance is also favored by the lack of body hygiene, as well as the consumption of medications such as B vitamins, barbiturates and amphetamines. Foods rich in protein (meat), spices, alcohol, cheese and coffee stimulate the activity of sweat glands and accentuate the smell of perspiration, altering its composition at the same time – which is why we should consume it in moderate amounts.
Abundant sweating can also be located in certain areas: shoulders, palms, soles, face. In this case, it usually starts at puberty and has a regression trend after the age of 40 years. Excessive sweating at the axles is specific to emotional people. Axillary hyperhidrosis is more pronounced in the summer and disappears during winter.
Palmide hyperhidrosis can be so high as to hinder activity in certain areas. Hands that are permanently wet can make it difficult for surgeons, electricians and all those who use their hands in their profession. Excessive palpitation is caused, in most cases, by nervous system problems: stress, emotions. When abundant sweat occurs both in the palms and in the face, it is often a sign of hyperthyroidism.
Plantar hyperhidrosis (soles) is the source of an ugly odor resulting from bacterial decomposition. When the sole is affected by hyperhidrosis, it becomes very sensitive to the pressure exerted during walking. Furthermore, contact dermatitis may occur with various allergenic substances in the footwear (paint, glue). Frequent washing, the use of absorbent powders, the avoidance of synthetic fiber stockings and the leather replacement shoe – which prevents the evaporation of sweat – are a necessity in this situation.
