Swayback - Lordosis

Lordosis refers to an abnormal bending of the spine. In lordosis, the curve of the spine arches forward.

What is going on in the body?

The normal spine has a slight degree of lordosis in the neck and lower back regions. It bends forward in the chest area. In excessive lordosis, there is a greater arching of the spine, especially in the lower back.

What are the causes and risks of the condition?

Specific causes of excessive lordosis include:

What are the signs and symptoms of the condition?

Lordosis often causes no symptoms, but it may be associated with increased strain on the lower back. This may cause low back pain. The buttocks appear prominent as a result of the excessive arching.

How is the condition diagnosed?

Lordosis is diagnosed based on a history and physical exam.

What can be done to prevent the condition?

There is no prevention for lordosis.

What are the long-term effects of the condition?

Lordosis that occurs in childhood usually corrects itself and is not a medical problem. If the lordosis does not correct itself, it can worsen if not addressed. Permanent lordosis may cause increased strain on the lower spine, with chronic low back pain.

What are the risks to others?

Lordosis is not contagious, and poses no risk to others.

What are the treatments for the condition?

Treatment is unnecessary when lordosis is minimal. Appropriate exercises and posture may help to reduce arching. In rare cases, a back brace or an operation may be needed.

What are the side effects of the treatments?

A brace may cause skin irritation. Surgery may cause bleeding, infection, or allergic reaction to anesthesia.

How is the condition monitored?

Periodic checkups can help assess the degree of lordosis and the flexibility of the back. Any new or worsening symptoms should be reported to the healthcare provider.
