Hello, my 17 yr old son has become a picky eater over the last 11 yrs. I’m very concerned because he is 5’6” and only weighs 90 lbs. We suspect he is on the autism spectrum because of the many symptoms he has shown throughout his life. He is sensitive to taste, texture, smell, someone else’s chewing....to where he won’t even put it by his mouth or has to leave the room. He’s picky about different brand tastes, who made the food, what pans were used, the number of items (he must have exactly 10 chicken nuggets or he will not eat any at all, even if he ate nothing all day. His is malnourished and refuses so much food that it’s only getting worse. Does anyone has similar issues, who do we see to get help?
