Unexplained Increase in Appetite: When to See a Family Doctor? - Family Medicine

Share to:

Recently, my appetite has increased for no apparent reason. Which specialty should I consult?


Recently, my appetite has increased.
I used to be satisfied with one bowl of rice for lunch, but now I can eat one and a half bowls and still feel hungry.
I don't think I'm eating less than my classmates at school, but I still feel hungry.
Since I eat slowly, sometimes I have to endure hunger and eat less, but in the afternoon, I end up buying snacks.
Why is this happening? If it were just about growing taller, that would be great, but I'm only 158 cm.
I'm worried that if I don't grow taller, I might end up gaining weight instead.
So, I'm hesitant to eat too much.
By the way, my lifestyle hasn't changed; everything is the same as before.

Hello, it is understandable that a 16-year-old like you may experience an increase in appetite.
I suggest you consider engaging in basketball, swimming, or other aerobic exercises.
This way, the increased caloric intake can be effectively converted into growth potential.
Wishing you good health from Tainan Hospital.

More Info


An unexplained increase in appetite can be concerning, especially if it deviates from your normal eating habits. It’s important to understand that changes in appetite can be influenced by a variety of factors, including physiological, psychological, and lifestyle changes.
Firstly, it’s essential to consider whether there have been any recent changes in your life that could contribute to this increase in appetite. Stress, anxiety, or emotional changes can often lead to increased cravings for food, particularly comfort foods. Additionally, hormonal changes, such as those that occur during puberty, can also affect appetite. Given that you mentioned your height and concerns about growth, it’s worth noting that during adolescence, the body undergoes significant changes that can lead to increased caloric needs as it prepares for growth spurts.

If your appetite continues to increase without any clear reason, it may be a good idea to consult with a family doctor. Here are some signs that indicate when you should seek medical advice:
1. Persistent Increase: If your increased appetite persists over several weeks and is accompanied by other symptoms, such as weight gain, fatigue, or mood changes, it’s time to see a doctor.

2. Weight Changes: If you notice significant weight gain or loss, this could indicate an underlying issue that needs to be addressed.

3. Physical Symptoms: If you experience other physical symptoms such as abdominal pain, nausea, or changes in digestion, these could be signs of a medical condition that requires attention.

4. Psychological Factors: If you find that your eating habits are affecting your mental health or leading to feelings of guilt or anxiety, it’s important to talk to a healthcare professional.

When you visit a family doctor, they will likely conduct a thorough assessment, which may include a physical examination, a review of your medical history, and possibly some laboratory tests to rule out conditions such as diabetes, thyroid disorders, or other metabolic issues that could be contributing to your increased appetite.

In terms of managing your appetite, here are some tips that may help:
- Mindful Eating: Pay attention to your hunger cues and try to eat slowly. This can help you recognize when you are truly hungry versus eating out of boredom or habit.

- Balanced Diet: Ensure that your meals are balanced with adequate protein, healthy fats, and fiber, which can help you feel fuller for longer.

- Stay Hydrated: Sometimes, feelings of hunger can actually be signs of dehydration. Make sure you are drinking enough water throughout the day.

- Regular Exercise: Engaging in physical activity can help regulate your appetite and improve your overall well-being.

In conclusion, while an increase in appetite can be a normal part of growth and development, it’s important to monitor your eating habits and any accompanying symptoms. If you have concerns, don’t hesitate to reach out to a family doctor who can provide personalized advice and support. Remember, taking care of your physical and mental health is crucial, and seeking help is a positive step towards understanding your body’s needs.
