If you are someone who is health-conscious, you probably keep a close watch on your body to notice any unusual or undesirable symptoms, right?

The truth is, our body can be affected by several health issues, and not every condition presents with clear or obvious signs. That’s why it’s always wise to stay alert, pay attention to changes, and remember the golden rule—prevention is better than cure.

Detecting a disorder in its early stages and seeking proper treatment can help prevent serious complications later. Often, even minor symptoms can signal dangerous conditions and, if ignored, may turn life-threatening.

One such symptom is numbness—a condition where a person loses sensation in certain body parts. Sometimes, it is also accompanied by a tingling feeling. While it may seem harmless at first, hand numbness can be linked to several serious health concerns.

Here are some possible causes:

# Tennis Elbow

A condition caused by the continuous wear and tear of elbow tendons, leading to arm pain and sometimes numbness in the hands.

# Hypothyroidism

When the thyroid gland fails to produce enough hormones, it can trigger a range of symptoms—including numbness in the hands.

# Alcoholism

Excessive alcohol consumption can damage nerves across the body, including those in the arms, leading to pain and hand numbness.

# Guillain-Barré Syndrome

An autoimmune disorder that damages nerves throughout the body, causing weakness, tingling, and numbness in the hands.

# Lyme Disease

A tick-borne infection that can affect the nervous system. Symptoms often include flu-like signs, fatigue, and hand numbness.

# Stroke

When blood flow from the brain to the hands is blocked, numbness in the hands can appear as one of the warning signs of a stroke.

# Ganglion Cysts

These small, non-cancerous cysts form on the tendons or nerves of the arms, leading to pain and numbness in the hands.
