Managing weight gain for kids with ADHD can be challenging, especially since stimulant medications often suppress appetite as a side effect. From personal experience and discussions with pediatricians, one helpful approach involves the medication Periactin (cyproheptadine). Although primarily an allergy medication, it has a notable side effect of increasing appetite, which can be a game changer for kids struggling to gain weight appropriately. When my child was diagnosed with ADHD and started on stimulant treatment, monitoring weight became a top priority. We noticed that while the medication helped with focus, it also reduced his interest in eating. After consulting with our pediatrician, Periactin was introduced under professional guidance. The improvement in his appetite was evident within a few weeks, and he began to gain weight steadily, easing concerns about undernutrition. It's important to remember that every child reacts differently to medications, so close collaboration with a healthcare provider is crucial. Beyond medication, integrating balanced nutrition tips—like offering small, frequent meals rich in protein and healthy fats—can further support weight gain. Parents and caregivers should also keep an eye on overall health, ensuring that increased calorie intake comes from nutritious sources to promote healthy growth and development. Combining these strategies has proven effective for many families managing ADHD-related weight challenges.
