When it comes to concerns about underweight children, it is essential to approach the situation with a comprehensive understanding of growth patterns, nutritional needs, and potential underlying health issues. Your son, at 9 years old, with a height of 119 cm and a weight of 19 kg, indeed falls below the typical growth percentiles for his age. This can be a cause for concern, and it is wise to consider seeking medical advice.

First, it is important to recognize that children's growth can vary significantly due to a multitude of factors, including genetics, diet, activity level, and overall health. The Centers for Disease Control and Prevention (CDC) provides growth charts that can help parents and healthcare providers assess whether a child's growth is within a healthy range. For a 9-year-old boy, the average weight typically ranges from about 22 kg to 36 kg, depending on height and body composition. Your son's weight places him below the 5th percentile, which indicates that he is significantly underweight for his age.

There are several reasons why a child may be underweight. These can include:
1. Nutritional Deficiencies: If a child is not consuming enough calories or the right balance of nutrients, they may struggle to gain weight. This could be due to picky eating habits, food allergies, or intolerances that limit their diet.

2. Metabolic Issues: Some children may have a higher metabolic rate, meaning they burn calories faster than average. Conditions such as hyperthyroidism can lead to weight loss or difficulty gaining weight.

3. Chronic Illnesses: Underlying health conditions, such as gastrointestinal disorders (e.g., celiac disease, Crohn's disease), diabetes, or infections, can affect a child's ability to absorb nutrients or maintain a healthy weight.

4. Psychosocial Factors: Emotional or psychological issues, including anxiety or depression, can also impact a child's appetite and eating habits.

Given these possibilities, it is advisable to consult a pediatrician. They can perform a thorough evaluation, including a physical examination, growth assessments, and possibly laboratory tests to rule out any underlying medical conditions. The pediatrician may also refer you to a pediatric nutritionist who can provide guidance on dietary changes that could help your son gain weight in a healthy manner.

In terms of what to expect during the visit, the pediatrician will likely:
- Review your son's growth history, including previous weights and heights.

- Discuss his eating habits, including what he typically eats in a day and any food preferences or aversions.

- Ask about any symptoms that may indicate health issues, such as gastrointestinal problems, fatigue, or changes in behavior.

- Possibly conduct blood tests to check for nutritional deficiencies or metabolic disorders.

It is crucial to approach this situation with care and support. Encouraging healthy eating habits without pressure, providing a variety of nutritious foods, and creating a positive mealtime environment can help. Additionally, involving your son in meal planning and preparation can make him more interested in food.

In summary, your concerns about your son's weight are valid, and seeking medical advice is a proactive step. A pediatrician will be able to assess his growth and health comprehensively and guide you on the best course of action. Remember, early intervention can make a significant difference in addressing any potential issues and ensuring your child's overall well-being.
