Re: T3/T4 Compound
In order to get a good answer to your question you have to post enough details for us to paint a picture. What dosage are you taking and what do your TSH, T3 and T4 test results look like? Since I don't have alot of info to go on, here are some observations of mine:
If you are undermedicated, you may still have problems losing weight or be gaining weight. T3 and T4 should be targeted to be in the middle of their lab ranges for MOST people, regardless of TSH (my opinion, which is shared by many agressive and sucessful doctors). If your doc insists on going by TSH, a TSH near or just below 1 would be a good target. For some people (myself included), TSH is entirely irrelevant.
Taking thyroid meds, even at the right dose for you doesn't mean you won't gain weight if your diet and lifestyle aren't healthy (this is in no way meant to point a finger, because I have no room to talk, since I am basically very lazy.) Make sure you are eating well (moderate amounts of fats and complex carbohydrates and good protein, limited simple carbohydrates and sugars) getting plenty of rest, and exercising, at least a few times a week.
Exercising may increase your need for thyroid meds and require you to increase your dose. Losing weight likely will decrease your need for thyroid meds further down the road, and eventually you will need to lower your dose again. This is why regular monitoring of your levels is important.
T3 is vital for protein synthesis (muscle growth). Since muscle tissue helps you burn more calories, it can keep you from gaining weight and/or help you lose weight. T3 does you no good for this, if you are not exercising, since no exercise means your muscle tissue is not stimulated to grow.
Eating too little can cause your metabolism to slow down making it even easier to gain weight/harder to lose it.
Other conditions such as Diabetes and Insulin Resistance are common in hypothyroid patients and can also cause weight gain. It might be worth looking into that, and at least monitoring your sugar levels.
Hopefully somethign here will help. If you can post the other info I asked for, maybe we can get a better ide of why you are still gaining weight.<p>[This message has been edited by Meep (edited 09-05-2002).]
