Do you sometimes feel that your child is a little shorter than other children of his age? Perhaps you are a little worried about this. Most of the time this can be normal, but in some cases there can be a medical reason for this. Today we are talking about such a condition, which is called 'dwarfism' or, in medical terms, `(Dwarfism)`.
Simply put, what is 'dwarfism'?
Dwarfism is a medical term. To be precise, it is a condition that belongs to a broader category called Skeletal Dysplasia. This is a condition that affects the growth of our bones and cartilage (the soft tissue between bones). There are hundreds of these conditions. As a result, a person's height is less than average. On average, a person with this condition is less than 4 feet 10 inches (1.47 meters) tall as an adult.
Some people like to use words like "little people" to describe people with this condition. But using words like "little people" is not appropriate at all. It can hurt their feelings.
This 'dwarfism' can come in different forms. For some people, it affects the growth of the arms and legs, for others, it affects the growth of the abdomen or head.
What are the main ways in which 'dwarfism' occurs?
Although there are hundreds of types of ``Skeletal Dysplasia`` that affect bone growth, there are a few main types that we see most often. Let's look at them in this table.
| Type | Brief Description |
|---|---|
| Achondroplastic dwarfism | This is the most common type. The main characteristics are short arms and legs and a protruding forehead. |
| Hypochondroplasia dwarfism | This is also a type of limb shortening, but it is a little milder. These features are not clearly visible during infancy. |
| Pituitary dwarfism | A condition caused by a deficiency of growth hormone in the body. |
| Primordial dwarfism | This is because the body size is small even before birth, that is, from the time the child is in the mother's womb. |
| Thanatophoric dysplasia | This is a rare, but very serious condition. The limbs become very short, and the chest becomes narrow. Babies can die almost immediately after birth due to breathing difficulties. |
Are 'Short Stature' and 'Dwarfism' the same thing?
This is something that confuses many people. Short stature is a common term. In other words, if someone is shorter than expected for their age, we call it 'short'. In the case of a child, if their height is below the normal growth curves or if they are shorter than the expected height based on their parents' height, they may be 'short'.
However, dwarfism is a specific medical condition that causes short stature. Not all short people have dwarfism.
Who can develop this condition? And is it common?
Dwarfism can affect anyone. Many types are genetic. That is, they can be inherited from parents. Some types are caused by random changes in DNA. Often, but not always, children with dwarfism are born to parents of normal height. You may be surprised to hear this, but it is true.
Dwarfism is a very rare condition. Even the most common type, achondroplasia, affects only about one in 15,000 to 40,000 people.
What are the symptoms of someone with 'dwarfism'?
The main and most obvious symptom is short stature. A person with this condition is less than 4 feet 10 inches tall as an adult. This short stature is more noticeable during childhood, adolescence, and adulthood than during adulthood.
'Dwarfism' can be divided into two types.
1. Proportionate: In this, the entire body is reduced in size by the same proportion.
2.Disproportionate: In this, the torso is of normal size, while the arms and legs are short.
Other common symptoms are:
- Bowed legs
- Flat nasal bridge
- Having a head larger than normal `(Large head)`
- Prominent forehead
- Short arms and legs
- Short fingers (hands and feet)
- Wide arms and legs
Other health problems that can cause these symptoms
Abnormal bone growth can sometimes cause other health problems.
- Accumulation of fluid around the brain (Hydrocephalus)
- Compressed nerves
- Scoliosis
- Frequent ear infections or hearing problems
- Pain in the knees and ankles
- Sleep apnea
Why does this happen? What are the causes of 'deafness'?
There are several possible causes for this condition. In most cases, it is a change in DNA. For some types, the exact cause is still unknown.
| Cause | A Simple Explanation |
|---|---|
| Family background | If the parents and other family members are short, it may be normal for the child to be short as well. |
| Genetic mutation | This condition can occur due to random changes in a person's DNA. |
| Growth hormone deficiency | The brain does not produce enough of the hormone needed for bone growth. |
| Late bloomer | Some children develop later than others, and there may be a family history of this. |
| Malnutrition | A child's lack of proper nutrition for growth affects height. |
| Low birth weight (small for gestational age) | Most babies who are born with low birth weight will reach normal growth within the first 2-3 years, but about 10% do not. |
Is this something that comes from genes? (Is it Genetic?)
Yes, some types of dwarfism are genetic. That is, they are caused by changes in DNA. But most of the time, these genetic mutations are random. That is, parents of average height are more likely to have children with dwarfism than those with short parents.
However, if one or both parents have dwarfism, the child is more likely to inherit it. For example, a mother or father with achondroplasia has a 50% chance of passing the condition on to their child. If both parents have achondroplasia, the child has a 50% chance of developing achondroplasia. There is also a 25% chance of developing a very severe condition called homozygous achondroplasia. This severe condition can cause the baby to die in the womb or shortly after birth.
If you are expecting a child and want to know if you are at risk for this type of genetic condition, it is very important to talk to your doctor about genetic testing.
How does a doctor diagnose the condition of 'dwarfism'?
In some cases, this condition can be detected before the baby is born, that is, during pregnancy. Prenatal screening tests can detect abnormalities in the baby's development.
After your baby is born, when you take your baby to the clinic every month, doctors and family health workers monitor the baby's growth. They measure the baby's height, weight, and head circumference and mark them on a growth chart. If your baby's growth is below the expected level, it could be a sign of this condition. Then, they do things like X-rays and blood tests to determine exactly what is causing the baby's growth failure.
What are the treatments for this?
There is no cure for this condition yet. However, there are many treatments that can help control the symptoms and make life easier. Treatment is determined by the type of dwarfism and symptoms each person has.
Surgical Treatments
- If bones grow in the wrong direction or are abnormally shaped, they can be surgically corrected.
- If there is excess fluid around the brain (hydrocephalus), it can be surgically removed.
- Reducing pressure on the brain stem.
- Removal of tonsils or adenoids to make breathing easier.
- Inserting small tubes into the ear to prevent ear infections.
Non-Surgical Treatments
- If you have sleep apnea , use a CPAP machine.
- Using hearing aids for hearing difficulties.
- Directing the child to a healthy diet and exercise to prevent overweight or obesity.
- If there is growth hormone deficiency , give growth hormone injections (hormone therapy).
- Recently, a drug called vosoritide (Voxzogo®) has been approved for children over 5 years of age with achondroplasia, whose bone growth has not yet stopped. Clinical trials have shown that it can increase the growth rate of children.
These treatments may be needed throughout life, but they can greatly improve their quality of life.
What will life be like with a child who has 'deafness'?
Although there is no cure for this condition, if the symptoms are treated properly, most people live a normal, healthy life. However, if your child has bone growth problems and requires frequent surgery, it can be a challenge for both the child and the family. Your doctor will provide the necessary treatment for your child and provide the guidance they need to live a full and healthy life.
The most important thing is that as parents, you should treat your child according to their age, not their height. This will build their self-esteem and help them feel loved and accepted.
Can a child's risk of developing this condition be reduced? How can the child be cared for?
Some types of dwarfism are genetic, so there's no way to prevent them. However, genetic testing can help you understand your risk. Talk to your doctor about it.
Nutrition is very important for the development of the baby. If you are pregnant, eat a balanced diet. After the baby is born, give him nutritious foods like protein, fruits, grains, and vegetables.
In addition to medical treatment, there are several things you can do to support your child:
- Setting up the home environment: Set up the home environment so that the child can work independently. For example, having a step stool or lowering the light switch a little.
- Provide psychological support: Provide educational and psychological support to the child to prevent and cope with bullying at school.
- Connect with people with similar experiences: Connect with organizations that support children and families with similar situations.
Take-Home Message
- Dwarfism is a medical condition that affects bone growth. It can have hundreds of causes.
- Most of the time, this is genetic, but it is often parents of average height who have children with this condition.
- Although it cannot be completely cured, symptoms can be treated and a full, healthy life can be lived.
- If you have any doubts about your child's development, see your doctor immediately and talk about it.
- The most important thing is to treat the child according to his age, not his height. That is very important for his mental health.
