Increased Appetite in Teenagers: Causes and Solutions - Nutrition

Eating, eating, eating, and can't stop?


Hello Doctor: I have a question to ask you.
My sister is in her first year of high school.
She is not overweight; she has a slim physique.
However, since starting high school, her appetite has increased significantly.
Even after she feels full, she still wants to eat more, and this has recently become more severe.
She has never experienced this before.
Why is this happening? What could be the cause? Is it binge eating disorder? Which specialist should she see? Please, I hope to get a reply soon...
Thank you.

Hello! During the first year of high school, girls are still in a rapid growth phase, and their bodies may require more calories, which can lead to increased hunger.
It's important to monitor for signs such as excessive eating and drinking, increased thirst, and sudden weight loss.
It is recommended to eat adequately while also maintaining sufficient physical activity.
If you still feel hungry after eating, consider whether other factors, such as stress, may be influencing your appetite.
If you have concerns, you can consult a physician in the metabolism department for an evaluation.
Wishing you good health.
This message is from Dietitian Tsai Hsiu-Wen at Nantou Hospital, Department of Health.

More Info


Increased appetite in teenagers can be attributed to a variety of factors, including physiological changes, psychological influences, and lifestyle habits. Understanding these factors can help in addressing the concerns you have about your sister's eating habits.

1. Physiological Changes: Adolescence is a period of rapid growth and development. During this time, teenagers experience hormonal changes that can significantly affect their metabolism and appetite. The body requires more energy to support growth, which can lead to an increased appetite. This is particularly true for teenagers who are physically active or involved in sports, as their energy expenditure is higher.

2. Psychological Factors: Emotional and psychological factors can also play a role in increased appetite. Stress, anxiety, and changes in mood can lead to emotional eating, where individuals eat not just for hunger but to cope with feelings. If your sister is experiencing stress from school, social pressures, or other life changes, this could contribute to her increased desire to eat.

3. Lifestyle and Dietary Habits: The types of food available and the eating environment can influence appetite. If your sister has access to high-calorie, low-nutrient foods, she may be more likely to overeat. Additionally, if she is eating while distracted (such as watching TV or using her phone), she may not be fully aware of her hunger cues, leading to overeating.

4. Potential Medical Concerns: While it’s less likely that your sister is experiencing binge eating disorder (BED), it’s important to consider that persistent changes in appetite can sometimes indicate underlying medical issues. Conditions such as hyperthyroidism, diabetes, or other metabolic disorders can affect appetite and should be ruled out by a healthcare professional.


Recommendations:
- Consult a Healthcare Professional: If your sister's increased appetite is concerning, it may be beneficial to consult a healthcare provider. A pediatrician or a family doctor can assess her overall health, discuss her eating habits, and determine if any further evaluation is needed. If psychological factors are suspected, a referral to a mental health professional may be appropriate.

- Encourage Healthy Eating Habits: Promote balanced meals that include a variety of nutrients. Encourage her to eat whole foods, such as fruits, vegetables, whole grains, and lean proteins, which can help her feel fuller for longer.
- Mindful Eating: Encourage your sister to practice mindful eating, which involves paying attention to hunger and fullness cues, eating slowly, and minimizing distractions during meals. This can help her develop a healthier relationship with food.

- Physical Activity: Regular physical activity can help regulate appetite and improve mood. Encourage her to engage in activities she enjoys, whether it’s sports, dancing, or simply going for walks.

- Monitor Stress Levels: If stress or emotional factors are contributing to her eating habits, it may be helpful to explore stress management techniques, such as mindfulness, yoga, or talking to someone about her feelings.

In conclusion, while increased appetite in teenagers can be a normal part of growth and development, it’s essential to monitor the situation and seek professional advice if it becomes concerning. By addressing the underlying causes and promoting healthy habits, your sister can develop a balanced approach to eating that supports her overall well-being.
