Hand problem

Common Causes of Numbness in the Hands

Many individuals experience occasional numbness in extremities due to posture and positioning while sitting or lying down. This type of numbness is typically the human body’s normal reaction to exerting weight and force on to certain nerves and areas of the body.

Ongoing, chronic, or debilitating numbness, however, is often caused by an underlying condition. The seriousness and risks associated with the numbness vary greatly depending upon the part of the body that is affected by the numbness and the underlying condition which is causing the symptom.

While numbness has been reported in nearly all parts of the human body, the hands are among the most common body parts associated with numbness, tingling, and sensations of “pins and needles”. Numerous conditions have the ability to cause numbness in the hands, though the most common include:

B12 Deficiency

Vitamin B12 plays a vital role in the overall function and health of the human body. Due to this fact, it is no surprise that a lack of B12 can cause problems such as numbness and tingling in the hands.

Individuals which do not consume Vitamin B12 through their diets (commonly those practicing vegetarian and vegan diets) are the most at risk for developing symptoms of B12 deficiency.

Peripheral Neuropathy

Commonly resulting from injury, infection, metabolic issues, hereditary conditions, and exposure to assorted toxins, peripheral neuropathy is an umbrella term for conditions affecting nerve function. These conditions often cause impairment of nerve function in the hands and feet, which may cause numbness, tingling, sensations, and weakness.

Type 2 Diabetes

Generally known as adult-onset diabetes, type 2 diabetes affects the human body’s process of metabolizing sugar, creating a resistance of the regulatory hormone known as insulin.

Among the many symptoms which type 2 diabetes is known to cause are numbness, tingling, pain, and sensations in the hands.


Surprising to many, the long term effects of the abuse of alcohol are known to cause many seemingly strange conditions in the human body, such as nerve damage, which in turn has the ability to cause numbness in the hands and feet.

Carpal Tunnel Syndrome

A condition affecting hundreds of thousands of Americans each year, carpal tunnel syndrome is often associated with various hand symptoms, including numbness and tingling.

While those performing repetitive movements of the hands on a daily basis are more likely to suffer from carpal tunnel syndrome, this condition is not always necessarily caused by movements of the hands.
