Excessive sweating (or hyperhidrosis) is a common problem, especially in:

  • Armpits,
  • Hands,
  • Foot.

Hyperhidrosis means that the person perspires more than normal, even if they do not:

  • There is heat and humidity,
  • Do exercises,
  • You have anxiety.

 

Sweat is usually mixed with the bacteria on the skin that cause the stench.
The acidic perspiration depends on several factors, in particular:

  • Hormones,
  • Food.

The smell of sweat also depends on how much time passes before you take a bath.

In the case of dermatitis or dermatosis caused by sweat (millet), the skin may become reddish and red blisters usually form .

 

Causes of excessive nocturnal or sleeping perspiration

Idiopathic hyperhidrosis
When a person has excessive sweating without a disease that causes it, idiopathic hyperhidrosis is said.
Hyperhidrosis can occur at any time during:

  • The childhood,
  • The teenage years,
  • The majority.

The disease is caused by the hyperactive sweat glands because they are more stimulated by the sympathetic (central) nervous system.

Sweat is often located :

  • On the soles of the feet,
  • In the armpits,
  • Some parts of the face,
  • In the groin,
  • On the palms
  • Beneath the breasts.

Menopause
During the perimenopause and menopause phase , the decline in estrogen causes an improper functioning of the hypothalamus.
This causes red skin and the dilation of blood vessels that causes excessive sweating.
Heat waves and heavy perspiration at night can occur even without:

  • A warm room,
  • A change in temperature.

 

Hyperthyroidism
The hyperthyroidism is an endocrine disorder characterized by an overactive thyroid.
This disease can accelerate the body’s metabolism, causing:

Hypoglycemia
Hypoglycemia is characterized by low blood sugar levels (<70 mg / dl) and affects patients with diabetes who take too much insulin.

Causes of hypoglycemia:

  • Waiting too long between meals,
  • Do not eat enough food,
  • A long training without eating.

Symptoms include:

  • Tremor,
  • Cold sweats,
  • Feeling of hunger,
  • Anxiety ,
  • Palpitations.

Nighttime hypoglycemia occurs during sleep and may be asymptomatic or cause:

  • Excessive sweating,
  • Wet bed linen,
  • Nightmares,
  • Insomnia ,
  • Headaches .

Infections
The tuberculosis is one of the most common causes of night sweats. This infectious disease that often affects a person’s lungs can cause:

There are many infections that can cause nighttime sweating, including:

  • Human immunodeficiency virus ( HIV )
  • Infection by mycobacterium avium complex
  • Infectious mononucleosis (caused by the Epstein – Barr virus )
  • Fungal infections – mycoses (coccidioidomycosis)
  • Abscess in lungs (necrosis of lung tissue)
  • Endocarditis ( inflammation of the heart valves)
  • Osteomyelitis (bone infection).

Medications that cause excessive sweating

  • Antidepressant Medications
    Selective serotonin reuptake inhibitors (SSRIs or SSRIs), tricyclic antidepressants, and psychiatric medications cause night sweats.
    Among the drugs that cause excessive sweating is sertraline (Zoloft)
  • Antipyretics
    Antipyretic medicines (for fever ), such as aspirin and paracetamol, can affect the hypothalamus.
    They induce the hypothalamus to lower the body temperature.
    Sweat is one of the mechanisms that are activated in response to the administration of these medications.
  • Other drugs:
    • Some medicines for blood pressure
    • Some medicines for dry mouth
  • Sleep apnea
    The sleep apnea occurs when there are repeated episodes of partial or complete obstruction of the upper airway during sleep.
    As the muscles of the thorax and the diaphragm act to open the airways, breathing resumes with a strong shudder.

Obstructive apnea can cause:

  • Night sweating,
  • Sleep disorders ,
  • Ronco,
  • Daytime fatigue,
  • Restlessness during sleep.

Cancer
Excessive sweating can also indicate certain types of cancer such as:

If excessive sweating is accompanied by fever and unexplained weight loss, it is best to consult a doctor to rule out the possibility of cancer.

Anxiety and stress
the anxiety and worry can cause a sudden night sweats.
The anxiety activates the warning system in the body.
This brings more blood to parts of the body that may need it.
The anxiety thus causes a narrowing of the peripheral blood vessels (vasoconstriction).
The consequence is that the body begins to sweat.
Sweating through an altered emotional state can be cold.

Heat Exhaust Heat 
exhaustion occurs when body temperature rises to more than 37 ° C (but less than 40 ° C).
Symptoms include:

Excessive sweating – hyperhidrosis

Eating
If a person eats a lot of fat, salty foods or simply eats a lot, it is easy to cause intense sweating in the armpits.
A simple and effective remedy consists of changes in diet:

  • Eat fruits and vegetables,
  • Avoid foods difficult to digest.

Who suffers from indigestion and goes to bed after a heavy meal, can wake up sweating with the wet sheets.

Taste sweating (Frey syndrome) occurs when a person chews, bites or sucks food.
This disease primarily affects the face and neck and can be caused by removal of the parathyroid glands or for no apparent reason.

Pregnancy
During pregnancy, perspiration increases due to hormonal imbalance and increased metabolism .
The more the woman eats, the hotter her body becomes.

Neurological problems Although neurological
diseases are very rare, they can cause nocturnal sweating. These include:

  • The autonomic dysreflexia is caused by spinal cord injuries between the fifth thoracic vertebra and those higher.
    The nerve impulses of the spinal cord are blocked by the lesion.
    Autonomic dysreflexia causes hyperactivity of the sympathetic nervous system.
    The symptoms of this disease are:

  • The cerebrovascular accident (CVA) is characterized by a loss of brain function caused by loss of blood supply to the brain.
    Often causes profuse hyperhidrosis and headache .

Among the other diseases that cause night sweats are:

  • Chronic Fatigue Syndrome
  • Diabetes insipidus
  • Disease Gastroesophageal Reflux
  • Chronic granulomatous disease (rare)
  • Chronic Eosinophilic Pneumonia
  • Prinzmetal’s angina (a rare variant of angina that occurs at rest)

 

Excessive perspiration on the face and head

Excessive sweating on the forehead can cause  embarrassment , for example because the hair gets wet, smells bad and can cause itching of the skin and scalp.

Causes of primary hyperhidrosis on the face
If the head has excessive primary sweating, there is no disease that causes it.
It is said that, in most cases, primary hyperhidrosis of the head is characterized by hyperactive sweat glands.

Causes of secondary hyperhidrosis Secondary
hyperhidrosis is the symptom of a disease.
There are some diseases that can cause excessive perspiration on the face, including:

 

Excessive sweating on hands and feet

Hyperactive sympathetic nervous system
In the event of a stressful situation, the body reacts by producing sweat to lower body temperature.
These situations can be:

  • Rage,
  • Stress ,
  • Nervousness ,
  • Dangers,
  • External heat and less ventilation,
  • Diseases of peripheral arterial and lymphatic vessels,
  • Because ,
  • Colic .

Sometimes there are cases of sweaty hands and feet in infants and children, which can be triggered by fever.

 

Excess sweating underarm

Factors contributing to underarm hyperhidrosis

  • Thyroid problems ( hyperthyroidism , hypothyroidism ), hypoglycemia, heat waves (menopause), and heart attacks;
  • Fever;
  • Consumption of spicy foods;
  • An excessive intake of caffeine;
  • Side effects of some types of analgesics, medicines for thyroid disorders or antipsychotic medications;
  • Stress , anxiety or depression .

 

Sweat on the buttocks and intimate areas

There are some parts of the body where the skin does not transpire because it is in contact with the surface of the chair or other body areas, which does not therefore depend on a disease.
This disorder affects for example:
1. Lumbar area;
2. Buttock;
3. Intimate zone;
4. Pubic region.

 

Natural Remedies for Excessive Sweating

If the problem of transpiration is genetic, a complete cure can not be expected; in other cases, it is possible to improve greatly with home remedies.

  • Apply the fresh lemon juice on the body parts that perspire more for 10-15 minutes, then rinse.
    Repeat every day. Rub the lemon slices over the area before showering.
  • Make a tea tree oil mixture (2 drops) with water.
    Fill a spray bottle and apply as a deodorant.
  • Dip a cotton ball into apple cider vinegar and apply on the underarm area.
  • Grind walnuts and eucalyptus leaves together to make a paste.
    Apply this paste on those parts of the body that perspire more. Leave it on for about 5-10 minutes. Then rinse well with water.
  • Avoid coffee and spicy food .

Select a home remedy and continue regularly for a period of about 1 month.
If you continue to sweat despite home remedies, you should see a dermatologist.

 

Treatment for excessive sweating and medications

General Tips

  • Wear clothes with breathable fabrics, such as sports-specific T-shirts.
  • Socks containing silver fiber or copper oxide reduce the smell.
  • Wear absorbent insoles on your shoes and replace them frequently.
  • Apply talc or baking soda after bathing.

Oral medications that reduce sweating are called anticholinergics.
An example is dicyclomine (Bentyl).
Most anticholinergics are only available with a prescription.
Side effects include dry mouth and blurred vision.

Antiperspirants
There are many antiperspirants available that block the sweat glands.
It is necessary to apply these substances at night in the body.
These antiperspirants enter the pores of the skin and block perspiration.

Among the most effective products are:

  • Thaty Deodorant Antiperspirant (natural extracts of cotton, marigold and melissa)
  • Deodorizantev Vichy – Antitranspirant Care 48h White and Yellow Antimanches
  • Antitranspirante Driclor

Spend the night.

In the feet the creams have a more limited effect because the skin is thicker.

Iontophoresis
This technique consists of applying a continuous, low-intensity current to the hands and feet.
Researchers do not know the mechanism of action, but it is believed that ionophoresis acts on nerves that cause sweat secretion.
Is used for:

  • Hands,
  • Foot,
  • Armpits

It is necessary to do this treatment for 20 minutes, at least once a week.
The problems of this treatment are:

  • Should be repeated in the long run,
  • It is not always effective.

Botox
Injections Botulinum toxin injections are performed in the area where the patient is excessively.
The toxin blocks the release of acetylcholine, which is a neurotransmitter. This substance is needed to stimulate the glands to produce sweat.
The treatment consists of 10 to 20 injections and the effect can last from 1 to 6 months.

Removal of the sweat glands
It can be done in a particular area such as the armpit.
Although this method is very useful, it is necessary to talk with the doctor about the side effects of the operation.

Thoracic sympathectomy
A surgical option for excessive sweating is called a thoracic sympathectomy.
This operation provides for the interruption of the sympathetic nervous system responsible for perspiration.
It is done by inserting a small endoscope under the armpit.
The goal is to cut off some small nerve fibers that control the sweat glands .
Thoracic sympathectomy is very effective, but at the same time it is risky.
The surgeon must temporarily collapse the lungs to see clearly the nerves.
The operation has some side effects, including:

  • Damage to nerves;
  • Compensatory sweating in other parts of the body not operated;
  • Respiratory complications;
  • Sometimes these disorders become permanent.
