Right first of all I have wrote posts on here before concerning my periods as it is now a year and still no period I have been diagnosed with an underactive thyroid and have been on medication for that since January, firs the past 16 days I have been dieting and exercising to see if that will bring back my periods but now every time I eat a meal I get diarrehea within 10mins of eating with really bad stomach cramps and sickness at first I thought maybe I am pregnant as this happened to me the first time I was pregnant I did a hpt yesterday morning but was negative I was just wondering if the medication I am on to control my thyroid could interfere with the pregnancy test the medication is called levothyroxine or if this could be something completely different
Any help would be appreciated thanks
Also where the periods are concerned I have now been referred to the fertility clinic at last!!

This website states that levothyroxine overdose can cause vomiting and diarrhea... check it out: Levothyroxine Information from Drugs.com (http://www.drugs.com/levothyroxine.html) Take care of yourself for now by drinking Gatorade to replenish electrolytes and call your doctor ASAP.

I haven't taken an overdose just one tablet a day

You may be taking too much for your body. Often times doctors will over prescribe in hopes of giving you what you want - to get the symptoms to go away.

Go to a different doctor and have your thyroid rechecked. Go to a an endocrinologist.

I am on the lowest amount prescribed 50mg just had my throid gland rechecked last week and it is fine now but will need to be on the tablets the rest of my life

That's what I was thinking Glinda... but since she is taking the lowest dosage available... hummm

So do you not think its anything to do with my dieting or exercising??

I don't think so... I think it has to do with your medication.

Yes I know I have thyroid disease as well. Trust me this stuff is confusing.

However having stomach problems like that is a cause for concern. I would get to the doctor to make sure nothing else is going on.

I don't understand I have been taking this medication since January and everythin has been fine up until like 10days ago

Are you taking any supplements, vitamins or anything like that.

I don't think its related to the medicine. I've been taking that same medication for over 18 years and never had that problem.

Do these tablets interfere in your hcg levels

Not taking anything else at all

I don't know what that is

If your not taking anything else I would get to the doctor. Diaherrea is no joke especially for 10 days.

It only happens when I eat a meal

Hcg is the hormone that detects pregnancy!

Hcg is a pregnancy horomone.

What about IBS?

What causes that?

It didn't say anything about hcg levels on the drugs.com website. You really need to consult with your health care professional ASAP and get all of this figured out. Diarrhea is dangerous if not taken care of properly.

what causes that?

IBS is irritable bowel syndrome. Here is a quote form webMD "The exact cause of irritable bowel syndrome (IBS) is not known. However, health experts believe faulty communication between the brain and the intestinal tract causes the symptoms of IBS." "A complex combination of elements, including psychological stress, hormones, the immune system, and chemicals called neurotransmitters, appears to interfere with messages between the brain and the bowel. The miscommunication causes abnormal muscle contractions or spasms, which often cause cramping pain. The spasms may either speed the passage of stool, causing diarrhea, or slow it down, causing constipation or bloating."

That's really helpful I think I am going to make an appointment to see my doctor cause all this is weird

Yeah it is! Hopefully all goes well! Make sure to mention possible "overdose" and IBS. You have to get stern with doctors sometimes.

You do with my doctors they are useless

If I were you, I would get another doctor's opinion on all of this. Sometimes things are seen differently in another's eyes.
