Why Do Some People Develop Hunchbacks?

Have you ever seen someone whose upper back is curved forward, almost like a hump? This is often called a hunchback. The medical word for it is kyphosis. It happens when the spine, especially the upper part, bends forward more than it should.


In this blog, Dr. Jayesh explains why some people develop a hunchback, what causes it, and how it can be treated. We’ll keep everything simple and easy to understand.

What Is a Hunchback?

Our spine is made of many small bones called vertebrae, stacked on top of each other. A healthy spine has natural curves that help us stand tall and move freely. But when the curve in the upper back becomes too much, it looks like a hump. This is called kyphosis or hunchback.

What Causes a Hunchback?

There are several reasons why people may develop a hunchback. Some happen during childhood, while others can develop later in life.

1. Poor Posture

This is one of the most common causes especially in teenagers and adults who sit a lot.

• ✓ Slouching at a desk
• ✓ Leaning over phones or laptops
• ✓ Carrying heavy backpacks

Over time, poor posture makes the spine curve forward more than it should.

2. Weak Back Muscles

If your back muscles are not strong, they can’t hold your spine in the right position. This can lead to a forward curve.


Lack of exercise, especially in older people, can cause muscle weakness and poor posture.

3. Osteoporosis (Weak Bones)

This condition makes bones thin and weak. It is common in older adults, especially women. When the bones in the spine become weak, they can collapse. This leads to a curved or hunched back.


People with osteoporosis may not even feel pain at first, but the hunch becomes more visible over time.

4. Spinal Injuries

Falls, accidents, or sports injuries can damage the spine. If the bones break or move out of place, it can lead to a hunchback.

5. Birth Conditions or Growth Problems

Some people are born with spine issues. Others develop problems during their teenage growth years.


A common condition is Scheuermann’s disease, where the vertebrae grow unevenly and cause a sharp curve in the upper back. It usually shows up in teenagers.

6. Infections or Tumors

Although rare, infections like tuberculosis or tumors in the spine can cause damage and result in a curved spine.

What Are the Signs of a Hunchback?

A person with kyphosis or a hunchback may have:

• ✓ A visible curve in the upper back
• ✓ Rounded shoulders
• ✓ Back pain or stiffness
• ✓ Feeling tired easily
• ✓ In severe cases, trouble breathing or walking

How Is It Treated?

The treatment depends on what is causing the hunchback and how severe it is.

1. Posture Correction

For mild cases caused by poor posture, simple steps can help:
