Help very Confused!

Hi everyone! Hope I'm in the right forum for my question...A little back ground first...ok. I had a hysterectomy (all but partial ovary gone) when i was 32 am now almost 39. I have always been a very small person 5'4 110-115lbs. with healthy appetite. Now my weight goes about 150 or more. I have gain this weight fairly quickly I think started about 6-8 mo. ago, but my appetite has decreased usually eat once a day, but not hungry. Now, here is to me the weirdest every time I eat I become extremely sleepy. I am very active and do not like this feeling of tiredness and though I admit I've wanted to gain a little more weight (was too skinny) this is getting ridiculous. I've went from a size 4 to an almost 14. Is this normal. Any help would be appreciated. Thanks

Did you get your thyroid checked?  I`m small like you and started gaining weight which would not budge!  Turns out I`m hypothyroid and now, after taking meds for about three  months, have dropped the excess weight around my stomach.  I`m older than you and perimenopausal which I think causes weight gain too.
Good luck!
