Weight loss...normal or not so normal?

Just curious, cause I'm bored, but I had a lil girl going on two years ago, but before I had her I was fit, weighed 135, mainly muscle...I was in the Army...but during my pregnancy I had gained a good 65 pounds, putting me at 200 when I delivered. After I delivered I dropped to 180...within that first year I dropped back down to the weight I was before I was prego..actually I'm two pounds lighter..so say I have a heart condition, a heart murmur and a pin size hole in my heart that leaks blood, plus some other abnormalities...would this weight loss seem normal?
