get checked: A TSH that low usually means the dose of synthoid might be too high.. Check with the doctor who put you on the meds to see what the next step is. ...Read more

Synthroid: Synthroid could cause this; however, it is unlikely since you've only been taking it for a week -- with the exception of the nausea. The anesthesia used for surgery may have some effect. In addition, your body is healing from the surgery and the release of certain hormones may be involve in this as well. Other medication may also contribute ( ie: post surgery antibiotics). ...Read more

I know that Synthroid is used for hypothyroidism but can it be used to increase appetite in people who eat too little?

No: It should not be used as an appetite stimulant. It will lead to more side effects, and actually suppress your own body hormone, which you may have enough. Extra thyroid hormone will increase your metabolism, your heart rate (leading to possible arrhythmias) and weight loss, diarrhea. Other medications are available as appetite stimulants. ...Read more

Can a doctor prescribe Synthroid to increase a patient's appetite?

Not wise: That would not be a good idea. A high dose of synthroid would increase metabolic rate (and put a stress on the heart) and appetite may/may not go up, but usually it would cause weight loss. Synthroid should only be prescribed for hypothyroidism, or other clear thyroid related conditions, and should not be used for obesity or appetite. ...Read more
