What is the reason why teenagers don't grow meat no matter how much they eat

It may be related to genetic factors, gastrointestinal malabsorption, hyperthyroidism, diabetes, parasitic infection and other reasons why adolescents can not grow meat even after eating. It is recommended to seek medical examination in a timely manner, clarify the cause, and make targeted adjustments.

I. Genetic Factors

Some adolescents have a high basal metabolic rate and fast energy expenditure due to family inheritance, making it difficult for them to gain weight even if they consume enough calories. This group of people usually have the characteristic of parents or close relatives being underweight, which can be improved by increasing the intake of high-quality protein and complex carbohydrates.

2. Gastrointestinal malabsorption

Chronic gastritis, lactose intolerance, and other digestive system problems can affect nutrient absorption. Common symptoms include postprandial bloating, abnormal bowel movements, etc., which need to be diagnosed through gastroscopy. When recuperating, you can choose easily digestible foods such as steamed eggs, yam Congee, and supplement pancreatin preparations when necessary.

III. Hyperthyroidism

Hyperthyroidism can lead to accelerated metabolic abnormalities in the body, manifested as overeating, emaciation, palpitations, and hand tremors. Diagnosis can be made through thyroid function examination, and medication such as methimazole is commonly used for control. Limit iodine intake in daily life and avoid high iodine foods such as seaweed and seaweed.

IV. diabetes

Type 1 diabetes is characterized by impaired glucose utilization due to insulin deficiency, which may lead to excessive drinking and eating but weight loss. Typical symptoms include increased nocturia and significant thirst, requiring insulin therapy. Diet should be timed and quantified, with priority given to low glycemic index ingredients.

V. Parasitic Infection

Intestinal parasites such as roundworms and hookworms can seize host nutrients, which may be accompanied by symptoms such as abdominal pain and anal itching. Fecal examination can confirm the diagnosis, and albendazole is commonly used for deworming. Pay attention to food hygiene in daily life, thoroughly clean vegetables and fruits, and fully cook meat.

It is recommended that parents regularly monitor their children's height and weight curves to ensure a sufficient daily intake of high-quality protein such as fish, eggs, and milk, paired with appropriate amounts of nuts and whole grains. To avoid blindly gaining weight with high sugar and high oil foods, appropriate resistance training can be performed to promote muscle growth. If continuous weight loss is accompanied by symptoms such as fatigue and fever, it is necessary to seek medical attention at a pediatric or endocrinology department as soon as possible to complete blood routine, thyroid function, glycated hemoglobin and other tests. Based on the examination results, the doctor may prescribe probiotics to regulate the gut microbiota or provide targeted supplementation of trace elements such as zinc and iron.
