There is a specific range of normal body weight based on height and body type. Having a hefty body type is not abnormal. But, sudden weight gain and obesity is a sure cause of worry. Earlier, there was a preconceived notion that obesity is only found in adults. However, in the recent years, it has been found that children and toddlers are also prone to weight gain. In fact, it is found that weight gain in children is one of the serious issues causing alarm in parents all over the world. Causes Improper eating habits and diet are the common causes of weight gain. Many parents are unaware of the unhealthy eating choices their children make while eating outside or at school. Secondly, as children are constantly exposed to fast and junk food, they tend to consume excess calories and fats. Eating disorders or overeating is another common reason. Unexplained weight gain can be a possible side effect of medications like antipsychotic drugs, corticosteroids, etc. Thirdly, children and teenagers may also gain weight during the onset of puberty. Girls are more likely to put on weight at the beginning of their menstrual cycle. On the other hand, complete lack of physical activity, being a couch potato, genetics, hormonal imbalance, etc., are some of the other possible causes. Treatment Options Being over weight or obese can make a child prone to high blood pressure and diabetes. Secondly, parents should also note that obesity can lower the morale of the child and lead to psychological problems. Eating disorders should be diagnosed by the doctor and treated accordingly. As a parent, you should go for healthy meal options and encourage the child to do the same. Secondly, if weight gain is caused due to medication or during puberty, you should consult the doctor to get the condition checked. Physical activity and exercise is a must for all toddlers, children, teenagers, and young adults to remain fit and healthy. Daily jogging, running, swimming, or any sports activity helps to get rid of the excess calories in the body and prevents weight gain. As lack of sleep and weight gain are also found to be interlinked, as a parent, you should keep a watch on your child's sleeping habits and patterns. Lastly, in case your child suffers from sudden and excessive weight gain, you should consult the doctor as soon as possible to get the condition diagnosed. Following the doctor's advice, diet, and exercise routine can be helpful. Take care! Disclaimer: This article is meant only to provide information.
