increased weight and fat in your abdomen can stretch your belly
and over time, you can develop tears in your abdominal wall lining and even weakness of the abdominal wall lining.
this can potentially lead to weakness in the lining of the abdomen and eventual hernias there.
your pains in your abdomen could be due to tears and strains of your abdominal wall lining.
joining a gym is a good start, but you have to continue to go as well as eat very smart to loose weight
you need to be checked for polycystic ovarian syndrome and have your thyroid hormone levels checked as well. PCOS and hypothyroidism can both cause weight gain and cause you difficulty with weight loss.
let me know if you have questions.
