More Info

---

Understanding why someone may be underweight despite normal eating habits can be complex and multifactorial. In your case, with a height of 162 cm and a weight of 37 kg, it is essential to consider various potential causes and solutions.


Possible Causes of Being Underweight
1. Metabolic Rate: Some individuals naturally have a higher basal metabolic rate (BMR), meaning they burn calories more quickly than others. This can make it challenging to gain weight, even with a seemingly adequate caloric intake.

2. Genetics: Family history plays a significant role in body weight. If you have relatives who are also naturally thin, it may simply be your genetic predisposition.

3. Nutritional Absorption Issues: Conditions such as celiac disease, Crohn's disease, or other gastrointestinal disorders can impair nutrient absorption, leading to weight loss or difficulty gaining weight despite eating normally.

4. Hyperthyroidism: An overactive thyroid can increase metabolism and lead to weight loss. Symptoms may include increased heart rate, anxiety, and excessive sweating.

5. Mental Health Factors: Conditions such as anxiety or depression can affect appetite and eating habits. Stress can also lead to changes in metabolism and weight.

6. Chronic Illness: Undiagnosed chronic illnesses can lead to weight loss or difficulty gaining weight. Conditions like diabetes, cancer, or chronic infections can significantly impact body weight.

7. Physical Activity: While you mentioned occasional exercise, if your activity level is high relative to your caloric intake, it could contribute to being underweight.


Solutions and Recommendations
1. Nutritional Assessment: Consider consulting with a registered dietitian or nutritionist who can assess your dietary habits and help create a personalized meal plan that ensures you are consuming enough calories and nutrients.

2. Increase Caloric Intake: Focus on calorie-dense foods that provide more energy without requiring large volumes of food. Examples include nuts, seeds, avocados, whole grains, and healthy oils. Incorporating smoothies or shakes can also help increase caloric intake.

3. Frequent Meals: Instead of three large meals, try eating smaller, more frequent meals throughout the day. This can help increase overall caloric intake without feeling overly full.

4. Strength Training: Incorporating resistance training can help build muscle mass, which may contribute to weight gain. Muscle weighs more than fat, and increasing muscle mass can improve overall body composition.

5. Monitor Thyroid Function: If you suspect hyperthyroidism or other hormonal issues, consult a healthcare provider for a thorough evaluation, including blood tests to check thyroid function.

6. Address Mental Health: If you feel that stress, anxiety, or depression may be affecting your eating habits, consider seeking support from a mental health professional.

7. Regular Check-ups: Regular medical check-ups can help identify any underlying health issues that may be contributing to your weight concerns. Discuss your symptoms and concerns with your healthcare provider.


Conclusion
Being underweight can be just as concerning as being overweight, and it is crucial to address the underlying causes. By taking a comprehensive approach that includes dietary adjustments, physical activity, and medical evaluation, you can work towards achieving a healthier weight. Remember, it’s essential to prioritize your overall health and well-being rather than focusing solely on the number on the scale.
