Pregnancy: I am sorry to hear about your miscarriages. Unfortunately I cannot say if you were carrying twins- were you pregnant? (Presume yes). I recommend you see an obstetrician to get evaluated for reasons for miscarriages and see that your thyroid is well managed. ...Read more

Thyroid requirements: can vary significantly during pregnancy and lab must be monitored closely. TSH's are commonly low or low normal in early pregnancy. A TSH of 4.75 is too high if you are attempting conception. Check w/your doctor. Make sure you are on brand name replacement for safety and consistency. ...Read more

Concerted effort: Effort under guidance is the best. I strongly recommend bariatric surgery; through a program though!. Teamwork including dietician, exercise therapist, sleep specialist, psychologist etc are generally needed for the success. The oft heard success stories on various diet commercials or exercise ones are less likely to be successful en masse, most likely to help is your motivation, diet &exercise. ...Read more

Has 2 miscarriages in 1 yr,at10th wk & 4th wk.Hv mild hypothyroidism n on synthroid (thyroxine).May hv low progesterone as blood test revealed.Can I take Vitex?

No enough Info.: According to company who makes Vitex, it is a herbal medicine that might act on the Pituitary gland. Even we consider their claim is true, the mechanism of the abortions in the first trimester is not that much related to LH and FSH. So I do not think using Vitex has that much impact on that.
