Our hands are intricate and complex organs that help us carry out numerous tasks throughout the day. Apart from being functional, our hands can also serve as a visual indicator of our overall health.
Various diseases can manifest in the hands, exhibiting specific signs and symptoms that can aid in their early detection. In this visual guide, we will explore six diseases that often leave their mark on our hands.
1. Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic autoimmune disease that primarily affects the joints. However, it can also cause visible changes in the hands. In the early stages of RA, you may notice swelling, redness, and a warm sensation in your hand joints.
As the disease progresses, nodules can form under the skin, typically near the knuckles. These nodules are often painless but can cause discomfort when pressure is applied.
2. Raynaud’s Disease
Raynaud’s disease is a condition characterized by reduced blood flow to the extremities, most commonly the fingers and toes, in response to cold temperatures or stress.
Although the symptoms primarily affect the fingers, they can also be observed in the hands. During an episode, your hands may turn white, then blue, and finally red as circulation returns. This phenomenon is often accompanied by numbness, tingling, and a cold sensation in the affected areas.
3. Dupuytren’s Contracture
Dupuytren’s contracture is a condition where the tissue beneath the skin of the palm and fingers becomes thick and tight. Over time, it can cause one or more fingers to bend toward the palm, making it difficult to fully extend them.
The disease typically affects the ring and little fingers but can involve others as well. It may start with the appearance of small nodules or pits in the palm, eventually leading to contractures that restrict hand movement.

4. Psoriasis
Psoriasis is a chronic, non-contagious skin condition that speeds up the life cycle of skin cells, causing them to build up rapidly on the surface. When psoriasis affects the hands, it often presents as red patches covered with silvery scales.
These patches can be itchy, painful, and may crack or bleed. The areas around the joints, including the fingers, are commonly affected. Nail changes, such as pitting, ridges, or separation from the nail bed, are also frequently observed.
5. Carpal Tunnel Syndrome
Carpal tunnel syndrome (CTS) occurs when the median nerve, which runs from the forearm into the hand, becomes compressed at the wrist. This compression can cause various symptoms, including pain, tingling, and numbness in the hand and fingers.
In some cases, individuals with CTS may also experience weakness or a loss of grip strength. Swelling and inflammation in the affected area can sometimes be visible, highlighting the presence of the syndrome.
6. Diabetic Hand Syndrome
Diabetic hand syndrome, also known as cheiroarthropathy, is a complication that can develop in individuals with diabetes.
Over time, high blood sugar levels can cause changes in the hands, such as thickened, tight skin that prevents full movement of the fingers. The appearance of the hands may be waxy, and it can become difficult to fully extend or bend the fingers. In severe cases, the limited mobility of the hands can affect everyday activities.
Conclusion
Our hands not only help us interact with the world but can also provide valuable insights into our health. Recognizing the visual signs associated with various diseases can contribute to early detection and intervention.
If you notice any unusual changes or symptoms in your hands, it is crucial to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
