I've started exersizing again and I've changed my eatting habit very drasticly

This past weekend I was sick all weekend.I lost 5pnds in 1 week.Do you think The dieting has to do with me getting sick?

    I agree with Meg. Your immune system may have been weakened by the lack of some kind of foods or if you are exercising in a gym, you may have picked something up there.

      That was the reason I was losing so much weight.I was just in the hospitals and was very sick.My weight has dropped 50 pounds since no dieting needed.I was diagnosed with acute hyper thyroid disease.
