At 16 years 7 months, your son is still in the growth and puberty phase, and variations in weight gain, body composition, and secondary sexual characteristics (like beard/moustache) are quite common. Since his reports (
TSH,
LFT, CBC) are normal, this is often related to growth pattern, metabolism, and nutrition rather than a medical issue.
Possible Reasons:
- High metabolism: Tall, lean adolescents often burn calories quickly, making weight gain difficult.
- Inadequate calorie intake: Even if he eats regularly, it may not be enough to meet his high growth and energy needs.
- Sensitive stomach: Digestive issues may affect intake or absorption, leading to lower weight gain.
- Delayed puberty (constitutional delay): Late development of beard/moustache and voice changes can be part of a normal variation in puberty timing.
Irregular eating habits or meal skipping can also contribute.
What You Can Do:
- Ensure frequent, nutrient-dense meals with adequate protein, carbs, and healthy fats.
- Support digestion with simple, home-cooked meals.
- Encourage light strength-building activities.
- Monitor growth over time rather than expecting rapid changes.
