Changes in the appearance of hands and nails can be an early indicator of underlying health problems. According to Professor John Lear, Consultant Dermatologist at Circle Alexandra Hospital in the UK, alterations in nail color, texture, and structure may reveal significant health concerns. Similarly, Dr. Zainab Lafta, a consultant dermatologist at HCA The Shard, the world’s largest private hospital group, explains that while some symptoms may be related to age or lifestyle, recurring or worsening symptoms require immediate medical attention.
Red Palms
Redness in the palms is usually not dangerous and may indicate anxiety or poor blood circulation. However, it can also signal skin conditions like eczema or psoriasis. In rare cases, red palms may result from liver diseases, cancer, or a hereditary condition known as palmar erythema. This condition can affect fingertips, nail beds, and sometimes even the soles of the feet. Additionally, red palms might indicate rheumatoid arthritis or a rare disorder called erythromelalgia, which causes burning pain, redness, and skin swelling.
Swelling Around Joints
Swelling in the joints and fingers can be a sign of osteoarthritis, rheumatoid arthritis, or gout. If accompanied by skin inflammation, it may point to psoriatic arthritis, which causes chronic joint pain, stiffness, and swelling. Swelling may also occur due to protein deficiency, thyroid disorders, or cellulitis, a bacterial skin infection. Diagnosis is crucial to treat the condition effectively. Maintaining a healthy weight and exercising regularly can help reduce symptoms. Corticosteroids may relieve psoriatic arthritis, while cellulitis can be treated with antibiotics.
Stiffness and Pain in Hands
Hand pain and stiffness can result from several conditions, including eczema, psoriasis, Raynaud’s syndrome, chilblains, and arthritis. Nerve compression in the wrist, known as carpal tunnel syndrome, can also cause pain. This condition is often triggered by repetitive hand movements, obesity, or diabetes. Keeping hands warm, avoiding tight clothing, and quitting smoking and alcohol can improve blood circulation and reduce pain.
Hand Tremors
Hand tremors can occur due to anxiety, fatigue, or excessive caffeine intake. However, they may also signal serious neurological issues. Parkinson’s disease, thyroid overactivity, or nerve disorders are potential causes of involuntary tremors. In some cases, nerve damage or deficiencies in essential nutrients can contribute to the problem.
Red, White, or Blue Fingertips
Raynaud’s syndrome, caused by the narrowing of blood vessels, leads to changes in fingertip color and a sensation of numbness or pain. This condition is often triggered by cold temperatures and may be an autoimmune response. Red fingertips can also indicate psoriasis, eczema, or paronychia, a bacterial or fungal infection around the nail bed. Wearing gloves and using medications can help alleviate symptoms.
Scaly Patches or Pustules
Scaly red patches and pustules on the hands may result from dermatitis or psoriasis. These conditions cause painful cracking, redness, and inflammation. Eczema leads to dry, itchy, and inflamed skin, while allergic contact dermatitis can cause blistering and scaling. Regular moisturizing and avoiding allergens like nickel, latex, or harsh soaps are recommended.
White Spots on Nails
White spots on nails, medically termed leukonychia, can occur due to minor trauma or zinc deficiency. They may also result from eczema or fungal infections. Excessive calcium deposits in the body can also cause white spots, but they are usually harmless. However, if the nails become brittle and flaky, it could indicate a fungal infection, which requires antifungal medication.
Yellow or Brittle Nails
Thickened yellow nails often indicate fungal infections such as onychomycosis. If the entire nail turns yellow, it may be linked to lung diseases. Brittle nails that grow slowly can be a sign of high cholesterol or deficiencies in vitamins or iron. Psoriasis and paronychia can also cause nails to become discolored and brittle. Consuming a diet rich in protein, iron, and zinc can help improve nail health.
Pitted or Grooved Nails
Small pits or grooves in nails may appear in people with eczema or thyroid disorders. Psoriasis can also cause nails to become ridged, thickened, and discolored. This may lead to onycholysis, where the nail separates from the nail bed. Since topical treatments are often ineffective on nails, light therapy is sometimes used in severe cases.
Key Advice
These signs are only indicative, and any persistent issues with hands or nails should be evaluated by a medical professional. Accurate diagnosis and appropriate treatment are essential for managing underlying health conditions. Following medical advice and using recommended medications can help alleviate symptoms effectively.
