Carpal Tunnel Syndrome: Causes, Symptoms and Prevention

In todays technology driven world  where typing, texting and using handheld devices have become an integral part of our daily lives issues related to repetitive strain injuries are on the rise. One such common ailment is Carpal Tunnel Syndrome (CTS). This article aims to provide a comprehensive understanding of Carpal Tunnel Syndrome including its causes, symptoms and preventive measures.

Carpal Tunnel Anatomy and Function

The carpal tunnel is a narrow passageway located on the palm side of the wrist. It houses the median nerve responsible for controlling sensation and movement in the thumb and first three fingers. The tunnel is formed by the wrist bones and a tough band of tissue called the transverse carpal ligament. When this tunnel becomes constricted or inflamed it leads to Carpal Tunnel Syndrome.

Causes of Carpal Tunnel Syndrome

Repetitive Hand Movements

Engaging in repetitive hand and wrist movements such as typing on a keyboard, using a mouse or performing assembly line tasks can strain the wrists delicate structures. Over time this strain can lead to swelling and compression of the median nerve.

Medical Conditions

Certain medical conditions such as diabetes, rheumatoid arthritis and thyroid disorders can increase the risk of developing Carpal Tunnel Syndrome. These conditions often lead to fluid retention and inflammation further narrowing the carpal tunnel.

Anatomical Factors

In some cases individuals might have a naturally narrower carpal tunnel. This anatomical predisposition can make them more susceptible to developing CTS even with less repetitive hand movement.


Pregnancy related hormonal changes and fluid retention can cause swelling in various parts of the body including the wrists. This increased pressure within the carpal tunnel can result in the compression of the median nerve.

Symptoms of Carpal Tunnel Syndrome

1. Numbness and Tingling

One of the hallmark symptoms of CTS is a tingling sensation or numbness in the thumb, index, middle and ring fingers. This sensation often occurs during activities that involve flexing the wrist like holding a phone or reading a book.

2. Weakness

Individuals with Carpal Tunnel Syndrome might experience weakness in their hand making it difficult to grasp or hold onto objects. This weakness can also extend to the forearm.

3. Pain

Pain, ranging from a dull ache to sharp discomfort is common in the wrist and hand. This pain might even radiate up the arm.

4. Nighttime Symptoms

CTS symptoms can worsen at night due to the natural tendency to flex the wrists during sleep. Individuals might wake up with numbness or tingling in their hands.

Preventive Measures

1. Ergonomic Workstations

Setting up an ergonomic workstation with proper chair height, keyboard position and wrist support can significantly reduce the risk of CTS.

2. Regular Stretching

Incorporating regular wrist and hand stretches into your routine can help maintain flexibility and prevent strain.

3. Mindful Hand Movements

Being conscious of your hand movements during activities can prevent unnecessary strain. Avoid excessive flexing or extending of the wrist.

4. Adequate Rest

Ensuring sufficient rest periods during repetitive tasks gives your wrists the time to recover.

5. Healthy Lifestyle

Managing underlying medical conditions like diabetes and arthritis through a healthy lifestyle can reduce the risk of CTS.


Carpal Tunnel Syndrome is a prevalent condition that affects millions worldwide. By understanding its causes, symptoms, treatment options and preventive measures individuals can take proactive steps to safeguard their wrist health. Through ergonomic practices, exercises and a mindful approach to hand movements we can mitigate the impact of this syndrome and continue to engage in our daily tasks comfortably.
