Clomid Effect on Glucose Levels?

Hello again,

Short version:

I have noticed significantly elevated glucose levels since starting clomiphene citrate. Is there a corelation?


Longer version:

I have posted a few times outlining the issues I am having with bad TRT approaches from my docs.

First, I was put on androgel 5g daily for a couple of months afterwhich my total t went from 360ish to 280ish. Then I was referred to an endo who said my total t is still in the normal range and took me off a-gel. I told the endo that I felt horrible and he said to stick it out and if my levels dont get back above 300, then we will talk again. He scheduled a total T test in 4 months (My HMO does not test for free-T).

After feeling horid for a few weeks presumably due to my diminished T levels, I decided to try to help my recovery along by taking clomiphene citrate (generic for clomid) 50mg daily. This was 10 days ago.

What I have not mentioned in those previous posts was that I was diagnosed with impaired fasting glucose last year (it was a glucose tolerance test where my glucose tolerance was “normal” but fasting glucose was high). Since that time, I have lost about 50lbs of fat and put on about 13lbs of muscle by eating right and training.

I have a glucose meter and check my glucose regularly. Typically, my fasting glucose levels would range mid 80’s to mid 90’s upon waking and I rarely had issues with my glucose during the day–even after eating. Almost always below 100. I take metformin 850mg twice daily.

Some time in early May, I began a ketogenic diet. I concluded the ketogenic diet at begining of July. Now, just before I stopped the ketogenic diet, I read about a temporary increase in insulin resistance (starvation diabetes) after a ketogenic diet. So, I have been introducing carbs slowly back into my diet. All through the month of July, my levels were a tad bit higher than prior to the ketogenic diet, but still about what I expected given the increased insulin resistance (fasting glucose between low 90s and low 100s).

However, what I noticed almost immediately after begining clomiphene is that my glucose levels have been a lot higher than they ever have been before.

Yesterday, for example, I had a high carb breakfast–which helped put me to sleep (that hasnt happened in a long time). After waking up (about 2.5-3.0 hour nap) I check my level and it was in the 140s. It took a few hours for it to come down to below 100.

There were several days where my levels ranged from 113-122 and the meals were relatively low carb (broccoli, humus, chicken, cottage cheese with protein powder for bedtime snack)

My levels have never been that high–even when I was first diagnosed and was drinking a 6 pack or two of beer a night along with all sorts of other garbage carbs and not working out. This is troubling because this is with my metformin. Indeed, yesterday I took 850mg three times.

I can’t find anything on the net that discusses clomid and glucose levels other than a few unanswered posts from pre/diabetic women with PCOS who have noticed the same effect on their glucose levels.

There was one mention on another forum about hormone level effect on insulin resistance, but it was in passing and nothing in detail.

Does anyone have any more information or thoughts on this? I have stopped clomiphene and am hoping this is transient (I also had vision issues the first few days which I didnt like). I have worked pretty hard thus far to prevent diabetes and it looks like this is a tremendous step backwards now.

sorry. wish I could help. No knowledge of glucose problems or Clomid.

How about seeing a registered dietitian and urologist with a specialty in andrology?

I took clomid for a month at half tab/d and felt like a million bucks. Brought my T from 240 to 790 ng/dl.

Thanks PC. I am hoping someone may be able to shed some light on this.

My guess is that most men who take this aren’t monitoring their glucose levels as regularly (daily) as someone with prediabetes (or diabetes). As a consequence, this effect may not be well known. This would explain why the few [unanswered] posts I’ve run across are from diabetic or prediabetic women who are experiencing the same issues I am (glucose readings out of whack).

In any case, clomid and other SERMs are not for long term use.

PubMed is your friend. You may be able to find a study done on animals. You have to be like Sherlock Holmes. Sometimes you can find a study that’s purpose is to find something else like Clomid’s effect on testosterone but they also collect a comprehensive metabolic panel.

Irony-Sitting in waiting room for my appt with a pituitary endocrinologist and posting my limited knowledge on this board :slight_smile:

Thanks all,

I have done some more searching and hit upon a thought I’d like to share.

My E2 levels when last tested was <12. My understanding is the range for men is 10-30. Assuming no issues translating my E2 reading into this range, this would be put in the low-normal range.

From what I have read, low estrogen negatively affects glucose metabolism.

Since clomid is a SERM, my understanding is that this would drive my estrogen levels down.

On top of this, I have been eating around 6-7lbs of broccoli a week (my primary veggie and snack) which also suppresses estrogen production.

In addition, my total t-levels are low normal (right now, god only knows what my free-t levels are) and low T-levels negatively affects insulin sensitivity. Not to mention the residual effects of coming off the ketogenic diet.

My conclusion is that perhaps my estrogen is below normal now as a result of the 7 days on clomid and when combined with the other factors outlined above, this could be an explanation for my whacky glucose readings of late.

Questions:

Are my facts and conclusion sound?
How long will it take the medication (clomid) to clear of my system?
Since I have stopped clomid (last dose was 3 days ago) and assuming nothing abnormal, what is a reasonable time expection for values returning to normal?
Is there anything I can do (naturally speaking) to help bring my E levels up?

Thanks!

P.S. Welcome back KSman. :slight_smile: Glad to see you back on the boards.

Clomid blocks the effects of estrogens on the hypothalamus, then your HPTA sees no or reduced estrogen feedback and LH/FSH are increased, T and E then increase. SERMs increase estrogen levels. Because of this, one always needs to taper off of SERMs to avoid estrogen rebound. Otherwise the SERM clears and the HPTA gets exposed the residual estrogens and is repressed.

SERMs increase estrogens [technically, clomid is chemically an estrogen]
Aromatase inhibitors reduce estrogens

Please post lab numbers, units and ranges if you can.

Wow! I dont think I could have been more wrong. I think I will need to read a little carefully in the future.

Thanks KSman.

I dont have any recent lab results as this is relatively new (i.e. 8-10 days old or so). I am going to ask for e2 and testosterone again (not sure how much static I will get). Do you have any other suggestions as far as labs?

there is a whole sticky with some great advice on recommended blood tests.

Thanks PC. I’ve seen the sticky and have tried to get all those tests. I run into resistance when I ask for all of them. So, I was attempting to be a little more specific and ask for a few of the most pertinent tests.

The resistance/availability of tests is one of the things I dislike the most about this HMO. I used to be able to ask my doc (under old plan) for just about any test and it wasnt much of a problem. The problem was getting the results. Under this plan, I can get the results usually within the 1-2 days, but I run into a lot of “you dont need that” etc, etc.
