Causes of Palmoplantar Hyperhidrosis

This condition can be triggered by various factors, including genetics, hormonal imbalances, emotional stress, and certain medical conditions. Heat, physical activity, and spicy foods can also exacerbate symptoms. Effective management strategies focus on reducing sweat production and improving quality of life.

Palmoplantar hyperhidrosis can be caused by overactive sweat glands in the palms and soles, leading to excessive sweating in these areas.
Hormonal changes, such as those occurring during puberty or menopause, can trigger palmoplantar hyperhidrosis in some individuals.
Certain medical conditions like hyperthyroidism or diabetes may contribute to the development of palmoplantar hyperhidrosis.
Genetics play a role in palmoplantar hyperhidrosis, as it tends to run in families and can be inherited.
Emotional triggers, such as stress, anxiety, or nervousness, can exacerbate palmoplantar hyperhidrosis symptoms in susceptible individuals.

Types Of Palmoplantar Hyperhidrosis

Palmoplantar hyperhidrosis can be classified into two types: focal and generalized. Focal hyperhidrosis mainly affects the palms and soles, while generalized hyperhidrosis involves excessive sweating all over the body. Both types can significantly impact a person's quality of life, causing discomfort and embarrassment. Treatment options are available to help manage symptoms and improve daily functioning.

Primary focal palmoplantar hyperhidrosis is the most common type, characterized by excessive sweating confined to the palms and soles without an underlying medical condition.
Secondary palmoplantar hyperhidrosis can be caused by various factors such as hormonal imbalances, medications, or medical conditions like hyperthyroidism or diabetes.
Emotional palmoplantar hyperhidrosis is triggered by stress, anxiety, or emotional stimuli, leading to uncontrollable sweating on the palms and soles during emotional situations.
Gustatory palmoplantar hyperhidrosis occurs when sweating is induced by eating certain foods, particularly spicy or hot foods, due to overstimulation of the autonomic nervous system.
Idiopathic palmoplantar hyperhidrosis refers to excessive sweating of the palms and soles with no identifiable cause or trigger.

Risk Factors

Risk factors for palmoplantar hyperhidrosis include genetics, with a family history of excessive sweating playing a role. Hormonal changes, such as puberty or menopause, can also trigger the condition. Certain medical conditions like thyroid disorders or diabetes can contribute to the problem. Additionally, emotional stress and anxiety can exacerbate palmoplantar hyperhidrosis symptoms. Keeping these factors in mind can help manage the condition effectively.

Genetics play a significant role in the development of palmoplantar hyperhidrosis, with a family history of excessive sweating increasing the risk.
Hormonal changes, such as those occurring during puberty or menopause, can trigger palmoplantar hyperhidrosis in individuals.
Obesity is a risk factor for palmoplantar hyperhidrosis, as excess weight can lead to increased sweating in the palms and soles.
Certain medical conditions, like thyroid disorders and diabetes, are associated with palmoplantar hyperhidrosis as a secondary symptom.
Psychological factors, including stress and anxiety, can exacerbate palmoplantar hyperhidrosis by triggering excessive sweating episodes.

Diagnosis of Palmoplantar Hyperhidrosis

To diagnose palmoplantar hyperhidrosis, your doctor will ask about your medical history and perform a physical examination. They may also conduct a starch-iodine test or a paper test to measure the extent of sweating. In some cases, additional tests like blood tests or imaging studies may be needed to rule out other underlying conditions. Based on these findings, your doctor will determine the appropriate treatment plan for managing your excessive sweating.

Patient history and physical examination: A detailed history of excessive sweating on the palms and soles, along with a thorough physical examination, can help diagnose palmoplantar hyperhidrosis.
Starch-iodine test: This simple test involves applying an iodine solution mixed with starch to the affected areas, which turns blue-black in the presence of sweat, aiding in the diagnosis of hyperhidrosis.
Quantitative sudomotor axon reflex test (QSART): QSART assesses the ability of sweat glands to produce sweat in response to stimuli, helping to confirm the diagnosis of palmoplantar hyperhidrosis.
Thermoregulatory sweat test (TST): TST involves inducing sweating by heating the body and measuring the sweat production in various body areas.

Treatment for Palmoplantar Hyperhidrosis

Treatment options for palmoplantar hyperhidrosis include topical antiperspirants, iontophoresis, oral medications, botulinum toxin injections, and in severe cases, surgery. Topical treatments can help reduce sweating, while iontophoresis involves using a device to deliver a low electrical current to affected areas. Oral medications and botulinum toxin injections can also be effective in managing excessive sweating. Surgery may be considered as a last resort.

Topical antiperspirants containing aluminum chloride are a common first-line treatment for palmoplantar hyperhidrosis, as they help to reduce sweating by blocking the sweat glands in the affected areas.
Iontophoresis involves using a device that delivers a mild electrical current to the palms and soles, which can help to temporarily decrease sweating by affecting the function of the sweat glands.
Botulinum toxin injections, commonly known as Botox, can be used to treat palmoplantar hyperhidrosis by blocking the nerve signals that stimulate sweat production in the treated areas, providing relief for several months.
Oral medications such as anticholinergics may be prescribed to help reduce sweating in individuals with palmoplantar hyperhidrosis by inhibiting the action of the neurotransmitter acetylcholine, which is involved in stimulating sweat gland activity.
