Does Sweaty Hands Cause Cold Feet? Hyperhidrosis Effects - Neurosurgery

More Info

---

Hyperhidrosis, or excessive sweating, is a condition that can significantly impact an individual's quality of life. It often manifests in the hands, feet, and underarms, leading to discomfort and social anxiety. Your experience of having sweaty hands during warmer months and cold feet during winter is not uncommon among those with hyperhidrosis.
The relationship between sweaty hands and cold feet can be understood through the body's thermoregulation and sympathetic nervous system responses. When the body is exposed to heat, it activates sweat glands to cool down. However, in individuals with hyperhidrosis, this response can be exaggerated, leading to excessive sweating in the hands and feet. Conversely, during colder months, the body may prioritize blood flow to vital organs, which can result in reduced circulation to the extremities, causing cold feet. This phenomenon is sometimes referred to as "cold extremities" and can be exacerbated by the body's inability to regulate temperature effectively due to the underlying condition.

Regarding surgical treatment for hyperhidrosis, procedures such as endoscopic thoracic sympathectomy (ETS) can be performed to reduce sweating in the hands. However, one of the potential side effects of this surgery is compensatory sweating, where the body compensates for the reduced sweating in the hands by increasing sweat production in other areas, such as the feet or back. Studies suggest that while some patients may experience a significant reduction in sweating (up to 50% or more) in the treated areas, others may find that compensatory sweating can lead to increased sweating in untreated areas. The degree of compensatory sweating varies from person to person, and it is essential to discuss these risks with your healthcare provider before proceeding with surgery.

As for your concern about persistent lower back pain, especially after prolonged sitting, this is a common issue, particularly among individuals who spend extended periods in a sedentary position. Poor posture, lack of movement, and muscle imbalances can contribute to discomfort and pain in the lower back. To address this, consider the following strategies:
1. Ergonomic Adjustments: Ensure that your workspace is ergonomically designed. Your chair should support your lower back, and your computer screen should be at eye level to prevent slouching.

2. Regular Breaks: Take short breaks every 30 to 60 minutes to stand, stretch, and move around. This can help alleviate stiffness and improve circulation.

3. Strengthening Exercises: Engage in exercises that strengthen your core and lower back muscles. A strong core can provide better support for your spine and reduce the risk of pain.

4. Stretching: Incorporate stretching into your daily routine, focusing on the hip flexors, hamstrings, and lower back muscles. This can help improve flexibility and reduce tension.

5. Physical Therapy: If your pain persists, consider consulting a physical therapist. They can provide personalized exercises and treatments to address your specific issues.

In summary, while sweaty hands and cold feet can be interconnected due to the body's thermoregulatory mechanisms, surgical interventions for hyperhidrosis may lead to compensatory sweating in other areas. Additionally, addressing lower back pain involves ergonomic adjustments, regular movement, and strengthening exercises. If symptoms persist, it is advisable to seek professional medical advice for tailored treatment options.
