Can invisible chronic illnesses be a problem durimg medical examination. I'm CR1 beneficiary and I have 6 non-contagious invisible chronic illnesses. I wear a Continous Glucose Monitor sensor (Freestyle Libre) for recurrent low blood sugar (I'm not diabetic) and still trying to discover what causes my condition with my Endocrinologist abroad, and I requiere to eat snacks every 2 to 3 hours, or I feel faint, I read at the medical exam and embassy interview agents don't allow any food. So how can I do this without calling the attention so much or getting a denial? Would you hide so many illnesses?
