Brief Answer:
Weight gain

Detailed Answer:
Sorry to note your weight issue.

I would like to know if the following test results are nomal:


And I would like to know the specific TSH and freeT4 values to be certain that your thyroid is adequately treated.

Secondly, there are 2 other rare causes of weight gain that are caused by hormonal disturbances.
Both are rare though.

The first is Cushings disease. An endocrinologist will need to examine you in person and see if this is a possibility. If there is suspicion for this, then there is a screening blood or saliva or urine test for this.

The second is called Acromegaly, in which there is excess growth hormone in the body.
The screening blood test for this is called IGF1.

Hi there - What is the relationship between growth hormone deficiency and low ferritin levels (anemia) and/or iron absorption? I have been diagnosed with low ferritin. My ferritin level was 3 in a normal range of 10-290. Oral iron would not bring my ferritin higher than a 7. It was determined that I was not absorbing iron properly. Therefore, I had been receiving iron via iv 100mg once per week over 6 months and the most my ferritin level would maintain was at 40. If I missed a week or two, my ferritin level would drop back to 10-20. In December (8wks ago), my doctor had me receive 1000mg at one time, instead of 100mg per week, and the plan was to have me wait 8-10 weeks. As of now, I haven't been back in 8 weeks. Also, in December I was diagnosed with adult growth hormone deficiency. I started growth hormone injections in early January and my most recent ferritin level was 474 (drawn Monday 2/14). At this level of 474, it appears I can stop my iron iv weekly, or otherwise, since my ferritin level is way too high now. Has the addition of hgh through the injections, and therefore the increase of hgh, improved my ability to absorb and/or maintain my ferritin levels? And, if so, what is the connection? Thanks so much! Robin

I'm 22 and about 5'8". I haven't grown since high school, but was wondering if there is any way possible to increase my actual height by 2-4". I had X-rays taken a couple years ago and was told my growth plates were still open. Cost not being a factor, is there any possible way to see this kind of increase my height, whether it be HGH or some other option?
