So far Ive been getting some crazy stretch marks with rapid weight gain, Ive put on roughly 40-50 pounds in a 2 month period and it's turned my stomach, thighs, crotch, and some of my arms into a mass of stretch marks. Im not sure how slow you have to go in order to avoid them, but I do know that puttin on pounds fast definitly brings them. Other than that things that tend to follow with rapid weight gain include, back pain, joint stiffness, obvious stretch marks, outgrowing of clothes, and people have had health problems, but I havent experience any so far.
