I am 17 years old, and for the last few years, after my weight loss of about 60lb, I have always been getting sick. I was a skinny kid growing up, borderline underweight, and then I suddenly gained a load of weight at 12 when puberty hit, then lost it at about 13-14. When I was growing up I only used to get sick maybe once every 2 years if even. Now its been progressively getting worse, after this one time I got strep throat at 15. I used to get sick once every 3-4 months, now its like once every 3-4 weeks! I go to the doctor and they test my blood and everything is fine but my immune system seems to be dead. However, I have to admit my weight sometimes fluctuates from about 130lb to 160lb, which may be putting a strain on my body. (i am 5'9", btw)
so my question is, what can I do to make my immune system stronger? Any suggestions would be beneficial at this point. Also, if I can post this in another section to recieve more replies, please redirect me. Thank you.
