What is Congenital Hypothyroidism?
- Congenital hypothyroidism is a condition where the thyroid gland (an organ in the neck) does not produce enough thyroid hormones, which are special chemicals needed for the body to grow and develop, right from birth.
- The thyroid gland is a small organ shaped like a butterfly that sits at the front of the neck. It makes thyroid hormones, which control how the body grows, how the brain develops, and how the body uses energy (metabolism).
- Without enough thyroid hormones, development can slow down.
- In India, congenital hypothyroidism is seen in about 1 in every 2000–4000 newborns.
Why Thyroid Hormones Matter?
You may wonder why a small gland is so important. Thyroid hormones affect almost every part of the body. They help in:- Brain development, especially during the first three years of life.
- Growth of bones and muscles.
- Regulation of metabolism (the way the body changes food into energy and manages body processes).
- Healthy skin, digestion, and nervous system function. Understanding these important roles sets the stage for learning what causes congenital hypothyroidism in babies.
Causes of Congenital Hypothyroidism
The condition can occur due to several reasons. In most cases, it is not caused by anything parents did or did not do. Common causes include:- Absent or underdeveloped thyroid gland: The gland may not form fully during pregnancy.
- Improper positioning of the thyroid gland: The gland may develop in an abnormal location in the neck.
- Inherited enzyme problems: Rare cases where the gland cannot make hormones properly.
- Iodine deficiency: Lack of iodine in the mother’s diet during pregnancy can affect thyroid hormone production.
- Maternal antibodies: Sometimes, antibodies from the mother can interfere with the baby’s thyroid function.
Signs and Symptoms in Babies
Many babies show no clear signs at birth. That is why newborn screening is important. However, in some cases, you may notice:- Prolonged jaundice (yellow skin and eyes lasting more than 2 weeks)
- Large tongue (tongue may stick out)
- Swelling around the eyes or face.
- Umbilical hernia (bulge at the belly button caused by a small hole in the muscles where the umbilical cord was attached).
- Lethargy or unusual sleepiness
- Constipation
- Poor feeding and slow weight gain
- Hoarse cry
- Cold or dry skin. Since early signs are not always obvious, the next section explains how newborn screening helps with detection in India.
Newborn Screening in India
- Newborn screening for congenital hypothyroidism is recommended across India.
- A small blood sample is taken from the baby’s heel within a few days of birth.
- This test measures levels of thyroid-stimulating hormone (TSH), a chemical that tells the thyroid to produce hormones, and thyroxine (T4), one of the primary thyroid hormones.
- If abnormal, doctors confirm with further blood tests.
Diagnosis
If screening shows abnormal results, further tests may include:- Serum TSH and T4 levels: These are blood tests to confirm how much thyroid-stimulating hormone (TSH) and thyroxine (T4) the baby's body has.
- Thyroid ultrasound: A safe scan that uses sound waves to make pictures of the neck, helping to see if the thyroid gland is there and where it is located.
- Thyroid scan: A special test that takes pictures of the thyroid gland to see its size, shape, and how well it is working.
Treatment Approach
The good news is that congenital hypothyroidism can be effectively treated. Treatment usually includes:- Daily thyroid hormone replacement, prescribed by a doctor.
- Regular monitoring of blood hormone levels, especially in the first few years.
- Adjustments to the medicine dose as the child grows.
Importance of Early Treatment
Early treatment makes a significant difference. If started within the first few weeks of life:- Growth and development progress normally.
- The risk of intellectual disability is significantly reduced.
- The child enjoys the same opportunities as other children.
Long-Term Care and Monitoring
Caring for a child with congenital hypothyroidism requires consistency and regular follow-ups. Here is what parents need to remember:- Do not miss doses. If missed, give as soon as remembered.
- Do not stop medicine without consulting a doctor.
- Keep follow-up appointments for blood tests.
- Watch for symptoms such as fatigue, weight changes, or poor growth, which may indicate the need for a dosage adjustment. Regular monitoring and attentiveness help your child thrive. Next, we’ll explore how you can further support their development beyond medical care.
How to Support Your Child’s Development
Along with medical care, your involvement makes a big difference. Parents can:- Encourage physical activity: Gentle exercises and play help healthy growth.
- Provide balanced nutrition: Ensure a diet with adequate protein, fruits, vegetables, and whole grains.
- Include iodine-rich foods: In India, iodised salt is a good source of iodine.
- Promote learning: Read, sing, and engage in conversation with your child daily to support their brain development.
- Track milestones: Keep a diary of physical, speech, and social milestones to share with your doctor.
Living with Congenital Hypothyroidism in India
Across India, awareness about congenital hypothyroidism is increasing. Here are some key points for parents:- Newborn screening is now available in many hospitals and should not be skipped.
- Thyroid medicine is affordable and widely available.
- With early care, children study, play, and live like others.
- Community support and awareness programmes are increasing in urban and rural areas.
Emotional Support for Parents
Caring for a child with a medical condition can feel overwhelming. Remember:- You are not alone; many parents face this journey as well.
- Early action brings positive outcomes.
- Sharing experiences with other parents can provide a sense of strength.
- Taking care of your own health and emotions is also important.

FAQs on Nurturing Little Lives: A Parent’s Guide to Congenital Hypothyroidism
- Can congenital hypothyroidism be prevented during pregnancy?
Not always. In most cases, it occurs due to thyroid development issues during pregnancy. However, ensuring adequate iodine intake during pregnancy helps reduce risk. - Will my child need treatment for life?
Most children require lifelong treatment, but in rare cases, temporary hypothyroidism can resolve. Your doctor will guide you based on follow-up results. - Can missing a few doses affect my child?
Missing occasional doses is not dangerous, but frequent misses can harm development. Always try to give the medicine daily without fail. - Is congenital hypothyroidism genetic?
It can sometimes run in families, but most cases occur by chance, without a family history of the condition. - Will my child be able to play and study like others?
Yes. With early treatment and regular care, children usually have normal growth, learning, and activity levels.
