Herniated (Slipped) Disc : Symptoms, Causes | Mediko.PH (2025)

Symptoms of Herniated Disc

The symptoms of a herniated disc vary depending on its location and severity. In many cases, a person may not experience noticeable symptoms. However, when a herniated disc compresses a nerve, it can lead to significant discomfort and neurological issues.

1. Localized pain. Pain occurs in the affected area of the spine, often worsening with movement, coughing, or sneezing.
2. Radiating pain. If the herniated disc presses on a nerve, pain may radiate to other areas, such as the shoulders, arms, hands, buttocks, or legs. This is called radiculopathy or sciatica when it affects the lower body.
3. Numbness or tingling. Affected nerves may cause sensations of numbness or tingling in the arms, hands, legs, or feet.
4. Muscle weakness. The compression of nerves can weaken muscles, making it difficult to lift objects, maintain balance, or perform normal daily activities.
5. Loss of reflexes. Some individuals experience reduced reflex responses in areas affected by the nerve compression.
6. Bowel or bladder dysfunction. In rare but serious cases, a large herniated disc in the lower spine can cause cauda equina syndrome, leading to loss of bladder or bowel control. This is a medical emergency requiring immediate treatment.

Mild cases of herniated discs can improve with rest and conservative treatment, but persistent or severe symptoms should be evaluated by a healthcare professional.

Diagnostic Procedures for Herniated Disc

Doctors use a combination of medical history, physical examination, and imaging tests to diagnose a herniated disc. Early diagnosis helps determine the severity of the condition and the most appropriate treatment plan.

1. Physical examination. A doctor assesses reflexes, muscle strength, walking ability, and the range of motion in the spine. They may also perform tests to identify nerve compression.
2. Medical history review. The doctor asks about symptoms, lifestyle habits, past injuries, and activities that may have contributed to the condition.
3. X-ray. While X-rays do not show herniated discs directly, they help rule out other spinal conditions, such as fractures or infections.
4. MRI (Magnetic Resonance Imaging). MRI scans provide detailed images of spinal discs, nerves, and soft tissues, making them the most effective tool for diagnosing herniated discs.
5. CT scan (Computed Tomography). CT scans provide cross-sectional images of the spine and are sometimes used when an MRI is not available or suitable.
6. Electromyography (EMG) and nerve conduction studies. These tests measure nerve function and help determine if nerve damage is caused by a herniated disc or another condition.

Once a diagnosis is confirmed, the doctor will recommend appropriate treatment options based on the severity of the symptoms and the patient’s overall health.

Complications of Untreated Herniated Disc

If left untreated, a herniated disc can lead to long-term health issues and significantly impact a person’s quality of life. While some cases improve with conservative treatment, severe or persistent cases may require medical intervention.

Possible complications of an untreated herniated disc include:

1. Chronic pain. Persistent nerve compression can cause ongoing pain in the back, neck, or affected limbs, making daily activities difficult.
2. Progressive nerve damage. Severe cases can lead to permanent nerve damage, resulting in weakness, numbness, or loss of coordination in the affected areas.
3. Loss of mobility. Pain and muscle weakness can make movement difficult, leading to reduced physical activity and muscle atrophy over time.
4. Cauda equina syndrome. A large herniated disc in the lower back can compress the cauda equina nerves, causing severe symptoms such as leg paralysis, loss of bladder or bowel control, and sexual dysfunction. This is a medical emergency requiring immediate surgery.
5. Spinal instability. Long-term disc damage can weaken the spine, increasing the risk of other spinal disorders such as degenerative disc disease or spinal stenosis.
6. Psychological effects. Chronic pain and limited mobility can lead to anxiety, depression, or reduced overall well-being.

Seeking early medical intervention can help prevent these complications and improve the chances of recovery.

Causes of Herniated Disc

A herniated disc occurs when the soft, gel-like center of an intervertebral disc pushes through a tear in the outer shell. Several factors can contribute to this condition.

1. Age-related degeneration. As people age, spinal discs lose their flexibility and hydration, making them more prone to tears and ruptures.
2. Repetitive strain. Frequent bending, twisting, or heavy lifting can put excessive stress on the spine, increasing the risk of disc herniation.
3. Improper lifting techniques. Lifting heavy objects incorrectly, especially with the back instead of the legs, can strain the spine and cause a disc to herniate.
4. Trauma or injury. Sudden impact from accidents, falls, or sports injuries can lead to disc rupture.
5. Obesity. Excess body weight increases pressure on the spine, particularly in the lower back, making disc herniation more likely.
6. Genetic predisposition. Some individuals have a genetic tendency for weaker spinal discs, making them more susceptible to herniation.
7. Smoking. Smoking reduces oxygen supply to spinal discs, weakening their structure and making them more prone to damage.
8. Prolonged sitting or poor posture. Sitting for long periods, especially with poor posture, can increase pressure on the spinal discs and contribute to disc degeneration.

Understanding these risk factors can help individuals take preventive measures to protect their spine.

Prevention of Herniated Disc

While not all cases of herniated discs can be prevented, maintaining a healthy spine can reduce the risk of developing this condition.

1. Practice proper lifting techniques. Always lift heavy objects using your legs, not your back, to avoid excessive strain on the spine.
2. Maintain a healthy weight. Excess weight puts additional pressure on the spine, increasing the risk of disc damage.
3. Engage in regular exercise. Strengthening core muscles helps support the spine and reduces stress on spinal discs.
4. Maintain good posture. Sitting and standing with proper alignment helps distribute weight evenly and minimizes strain on the back.
5. Avoid prolonged sitting. Taking breaks to stand and stretch helps relieve pressure on spinal discs, especially for individuals with desk jobs.
6. Quit smoking. Avoiding tobacco use improves oxygen supply to spinal tissues and reduces the risk of disc degeneration.
7. Use supportive footwear. Wearing comfortable shoes with good arch support can help maintain spinal alignment and reduce strain.
8. Stay hydrated. Proper hydration helps keep spinal discs flexible and resilient.

By adopting these healthy habits, individuals can reduce their risk of developing a herniated disc and maintain overall spinal health.

Types of Herniated Disc

Herniated discs can be classified based on their location and the severity of the herniation. Understanding these types helps determine the best treatment approach.

Types of herniated discs include:

1. Cervical herniated disc. Occurs in the neck (cervical spine) and can cause pain, numbness, or weakness in the shoulders, arms, and hands.
2. Thoracic herniated disc. Found in the upper and middle back (thoracic spine), this type is rare but can cause pain radiating around the ribs or chest.
3. Lumbar herniated disc. The most common type, occurring in the lower back (lumbar spine), often leading to sciatica and leg pain.
4. Contained herniation. The disc bulges outward but remains intact, potentially pressing on nerves or the spinal cord.
5. Non-contained herniation. The disc’s inner material leaks out, irritating nearby nerves and causing more severe symptoms.

The type and severity of the herniation influence treatment options, ranging from conservative care to surgical intervention.

Degrees of Disc Herniation

Disc herniation is classified into different degrees based on the extent of disc damage and the displacement of disc material. Understanding these degrees helps clarify the severity of the condition and guides treatment decisions.

1. Disc bulge. The disc’s outer layer (annulus fibrosus) weakens and protrudes slightly outward but remains intact. It often causes mild symptoms or no symptoms at all and may not press on surrounding nerves.
2. Disc protrusion. The nucleus pulposus (gel-like center of the disc) pushes outward but is still contained within the annulus fibrosus. This can cause pain and nerve compression if the protruding portion presses on a nerve.
3. Disc extrusion. The nucleus pulposus breaks through the outer layer of the disc, resulting in a significant outward bulge. The herniated material remains connected to the disc, but this degree of herniation often causes severe symptoms due to nerve irritation.
4. Disc sequestration. The nucleus pulposus escapes the disc entirely and becomes a free fragment in the spinal canal. This is the most severe form of herniation and can result in severe nerve compression, leading to symptoms such as extreme pain, muscle weakness, and loss of bladder or bowel control.

The degree of disc herniation determines the appropriate treatment plan, which may range from conservative measures like physical therapy and rest to more aggressive interventions, such as surgery. Early diagnosis and treatment can help prevent further damage and improve recovery outcomes.

Risk Factors for Herniated Disc

Several factors can increase the likelihood of developing a herniated disc. Some of these factors are preventable, while others are due to genetics or aging.

1. Aging. The spinal discs lose water content and elasticity over time, making them more prone to herniation.
2. Genetics. Some individuals have a family history of spinal conditions, increasing their risk.
3. Occupation. Jobs that involve heavy lifting, repetitive movements, or prolonged sitting can contribute to disc damage.
4. Obesity. Excess body weight places additional stress on the spine, particularly the lower back.
5. Smoking. Smoking reduces oxygen supply to the spinal discs, accelerating degeneration.
6. Poor posture. Sitting or standing incorrectly for long periods increases strain on the spine.
7. Lack of physical activity. Weak core muscles provide less support to the spine, making it more vulnerable to injury.

Managing these risk factors can help reduce the chances of developing a herniated disc and promote spinal health.
