Thus, it is important to have knowledge about the causes, symptoms, as well as the treatments for hypohidrosis, especially when eating a fruit that may contribute to the condition.

Hypohidrosis: What is this condition?

Hypohidrosis, also known as Anhidrosis, is a condition which is commonly characterized by the inability of the body to sweat properly. This may lead to the body withholding bodily fluids that would otherwise be eliminated through perspiration. This also means that the toxins in the body that are usually eliminated via sweating are not capable of leaving the body, which can be a dangerous situation.

In addition, sweating is an essential process of the body, which enables us to cool our bodies. When a body is not able to regulate the internal temperature in this particular way, it may overheat and lead to heat exhaustion or heat stroke, which could be deadly.

Occasionally, hypohidrosis may just affect a particular part of the body. This is not that dangerous, since the sweat can still leave the body. However, this must still be taken seriously because the condition may get worse and become dangerous. If the entire body is not able to sweat, then your life may become at risk.

Symptoms of Hypohidrosis or Anhidrosis

The most common symptoms of Anhidrosis include:

  • Feeling hot
  • Flushing
  • Weakness
  • Dizziness due to the overheating of the body
  • Lack of or less sweating in response to heat

The absence of sweating can be localized, generalized, or can be seen is various patches. Some areas that sweat may overcompensate for the lack of sweating in various parts of the body, resulting in some body parts producing copious amounts of sweat, while others produce none. The generalized hypohidrosis affects most of the parts of the body.

When the body fails to cool in a proper manner, it may lead to heat stroke and heat exhaustion. Primarily, after doing physical exertion or as a response to hot weather. The hypohidrosis may develop as an illness on its own or it may be associated with some other conditions, like skin injury or diabetes.

Causes of Hypohidrosis or Anhidrosis

The condition occurs when the sweat glands in the body don’t work properly at all.

Here are some possible reasons for this:

  • Clogged sweat gland ducts because of bacterial infections or dead skin
  • Scleroderma or systematic sclerosis. This progressive autoimmune diseases may cause the skin to tighten and get harden.
  • Trauma to the sweat glands.
  • Skin damage or skin conditions, including leprosy and severe burns.
  • Horner syndrome, which is caused by damage to the sympathetic nervous system in the neck.
  • Lung cancer, which may cause hypohidrosis on one side of the body.
  • Sjorgren’s syndrome, a chronic disorder of the immune system that may affect the proper functioning of the sweat glands, leading to hypohidrosis.
  • Trauma to the nerves that control the sweating.

Risk Factors for Hypohidrosis

Apart from older age, there are some more factors that may increase the risk of Anhidrosis, including the following:

  • Skin conditions, like psoriasis and various types of rashes.
  • Diabetes, which may affect the sweat glands.
  • Genetic mutations, which may change the genes and cause some abnormalities, leading to improper functioning of the sweat glands.

Treatments for Hypohidrosis or Anhidrosis

If you already have started experiencing various symptoms of heat exhaustion, you may try to find a much cooler location for as long as possible. For an instance, if you are outside, you should try to look for a shady area to rest in. It may also be beneficial to lie down and stop all strenuous activity.

There are some home treatments for hypohidrosis that may help, including the following:

  • Cucumber juice: This may improve sweat production, thus, increasing hydration.
  • Baking soda: This is beneficial in increasing a person’s ability to sweat by increasing the capillary flow. This is one of the easiest-to-find home treatments for hypohidrosis.
  • Soybean and ginger supplements: Adding these to the diet plan may help in improving the blood flow as well as promote proper perspiration.
