These days, rapid weight gain in young children is becoming a cause of concern for many parents. People often dismiss it as a result of overeating, junk food, or lack of exercise. However, health experts say that sudden weight gain can sometimes be a sign of a serious condition like thyroid disease. Especially if a child’s weight gain is accompanied by fatigue, lethargy, and weakness, it’s important to be cautious.
The thyroid is a small, butterfly-shaped gland located in the front of the neck that controls many vital body functions. This gland produces hormones that regulate children’s growth, brain development, and body metabolism. When this gland doesn’t function properly, it can lead to various problems.
The most common thyroid problem in children is hypothyroidism. This means the thyroid gland is producing less hormones than necessary. According to health experts, the most common cause is an autoimmune disease called Hashimoto’s thyroiditis, which often runs in the family.
Dr. Naeem Mitre, Pediatric Endocrinologist, explains that some children may be born with this condition, known as congenital hypothyroidism. In others, the condition develops as they grow older. These children may experience symptoms such as gradual weight gain, constant fatigue, constipation, feeling cold, dry hair, and poor concentration.
According to doctors, mere weight gain isn’t always a sign of thyroid disease. However, if a child becomes lethargic and obese, or their growth is affected, it’s important to get tested. Sometimes, swelling in the neck or an enlarged thyroid gland may also be present. This can be diagnosed with a simple blood test. Health experts also say that children can suffer from hyperthyroidism. This condition causes the thyroid to produce excessive hormones. These children may experience symptoms such as rapid weight loss, increased anxiety, irritability, frequent diarrhea, and bulging eyes.
If left untreated, thyroid can affect both a child’s physical and mental growth. In severe cases, problems like academic performance, stunted height, and persistent weakness can occur. Doctors say that thyroid is treatable. In most cases, children are given a daily medication to maintain hormonal balance. Therefore, if a child’s weight is suddenly increasing or unusual changes are observed in their body, it is important to consult a doctor promptly rather than ignoring it.
