I might have thyroid issues that arent showing up on bloodwork,ive gained weight, taking kelp and now losing weight, so is it thyroid if im losing?

Seems likely: Many with hypothyroidism have "normal" thyroid tests- see http://tinyurl.com/cseyehk and http://tinyurl.com/nrww2qg and https://www.verywell.com/signs-of-a-thyroid-problem-3231530 Iodine deficiency is a common cause; if taking kelp corrects the problem that is better than taking thyroid hormone! Please reconsider statin use- see http://tinyurl.com/43vtf67 & http://tinyurl.com/p48fhko & comment: ...Read more

I am having underactive thyroid function & I am on thyroxine medication but I am struggling to lose weight. Is there any  fast acting detox program?

Consider T3, (liothyronine) No but: Many people find that thyroxine does not adequately treat their hypothyroidism and benefit from t3 (liothyronine) or natural thyroid- see http://bit.Ly/15k26u8 ; http://abt.Cm/18gpb3a it is impossible to clear years of toxin accumulation overnite- it's a long process.

Is it possible i can’t gain any weight cause i may have low testosterone? I am 110 pounds.

Is it possible i can’t gain any weight cause i may have low testosterone? I am 110 pounds.

Possible : Possible but not likely. Besides low testosterone, infections such as intestinal worms/parasites, TB & hiv/aids, cancer, hyperthyroidism, and other chronic disease conditions can sometimes make it difficult to gain weight, although that isn't usually an issue in this country. Don't forget that nutrition plays a major role in weight gain/loss. We usually estimate that 3, 500 calories (kcal) equals one pound of weight. In other words, energy in has to exceed energy out by 3, 500 calories for their to be a one pound weight gain. Likewise, there also has to be a net 3, 500 calorie loss with energy out exceeding energy in for their to be one pound of weight lost. Finally, while we use body mass index (bmi) to diagnose normal vs overweight vs obese vs morbidly obesity, that calcuation doesn't take into account sex, bone structure, and fat vs muscle. In fact, it's better to be a lean 110# rather than a fat 110#. Regardless, go talk to your family physician about appropriate testing & diagnosis. Good luck! ...Read more

Can metformin cause weight loss even though I am on Synthroid (thyroxine) 115 after having thyroid cancer 3 years ago . I am 5 ft8!150 lbs. I am a smallmeater but?

Metformin: Metformin is considered a weight neutral drug.. In clinical trials, the typically weight loss is around 2 kg. The main advantage for metformin is that it does not cause weight gain which is what we always worry about with diabetes drugs. Your bmi is 22.8 which is excellent. I wouldn't worry about it. ...Read more

Ok im not gaining weight and if I do I lose it fast have been diagnosed with hypothyroidism, also im loosing my hair fast too?

Thyroid and weight: Given your question i feel that you need to have a visit with your medical provider and have some more labs drawn. The inability to gain weight seems like too much thyroid....If that is the culprit. But, the other symptoms, the hair loss seems more likely a low thyroid. So, not much more to say here in this forum but please get some new blood tests. ...Read more
