Excessive head sweatça: what can it be and what to do

Excessive head sweating is caused by a condition called hyperhidrosis, which is the excessive release of sweat. Sweat is the body's natural way of cooling itself and it is a process that takes place throughout the day, but it is not noticed, since hyperhidrosis is the increased form, that is, the glands release much more sweat than the body needs. to cool off.

Hyperhidrosis most often has hereditary causes, that is, more people in the same family can have it. However, there can also be situations such as high temperatures and the use of some medicines, which can temporarily increase the release of sweat, but this does not mean that the person has hyperhidrosis. In addition, in situations of high stress, fear or severe anxiety, those who tend to sweat in a normal amount may also experience excessive sweating.

However, and although more rare, there is also the possibility that excessive head sweating is a sign of poorly controlled diabetes, in which case hyperhidrosis usually improves with glycemic control.

How to confirm it is hyperhidrosis

The diagnosis of hyperhidrosis is made by the person's report, but the dermatologist may request the iodine and starch test, to confirm if it really is a case of hyperhidrosis.

For this test, an iodine solution is applied to the head, in the area where the person reports most sweat, and left to dry. Cornstarch is then sprinkled over the area, which makes the sweating areas appear dark. The iodine and starch test is only necessary to accurately confirm the foci of hyperhidrosis in the head.

The dermatologist may still order laboratory tests, such as a blood count, to detect diabetes or lack/excess of thyroid hormones, if they suspect the cause of hyperhidrosis which may just be a symptom of another disease.

How the treatment is done

Treatment with medication has positive results and most of the time the excessive sweating on the head disappears. However, in some cases the dermatologist may refer the person to surgery if the drugs do not have the necessary effect.

Treatment is usually done with drugs such as:

  • Aluminium chloride, known as Drysol;
  • Ferric subsulfate also known as Monsel's solution;
  • Silver nitrate;
  • Oral glycopyrrolate, known as Seebri or Qbrexza

Botulinum toxin type A is also a way to treat hyperhidrosis. In these cases, the injection is made in the area where the sweat is more intense, the procedure lasts about 30 minutes, and the person returns to normal routine on the same day. Sweating tends to decrease after the third day after botulinum toxin application.

If treatment with drugs or botulinum toxin does not show the expected results, the dermatologist can refer you to surgery, which is performed with small cuts in the skin and lasts about 45 minutes. Learn how surgery to stop sweating is performed.

What can be baby head sweating

Babies tend to sweat a lot through their heads, especially when breastfeeding. This is a normal situation, as the child's head is the place on the body with the most blood circulation, making it naturally hotter and prone to sweating.

Also, babies make a lot of effort to suckle, and this raises their body temperature. The proximity of the baby's body to the lap of the breast at the time of breastfeeding also causes the temperature to rise, as the baby does not have the mature thermoregulation mechanism, which is when the body is able to cool or warm up to maintain the temperature as close as possible. possible from 36°C.

To avoid excessive sweating on the baby's head, parents can dress the child in lighter clothes at the time of breastfeeding, for example, however, if the sweat is very intense, it is recommended to take child to the pediatrician, as tests may be necessary to verify that sweating is not a symptom of another disease that needs more specific treatment.
