Help interpreting test results

Hey everyone!

I'm a 20 year old student and today my doctor told me that me that I (likely) have celiac disease. To confirm the diagnosis, she's ordering an endoscopy, but I'm not sure how long this will take due to wait-times. She told me to cut gluten out of my diet, but I've also read that you should still eat gluten leading up to the endoscopy. Basically, I want some help interpreting my bloodwork results to see if it's very likely I have celiac disease, and if I should start cutting gluten or wait an indefinite amount of time for the test.

Hi Armadillo and welcome to the forum!

I'd agree with your doctor looking at those figures.

It is usual for patients with suspected celiac disease to have a follow-up endoscopy to confirm the diagnosis.  It is important to continue eating gluten before the endoscopy - as I understand it, that's about two slices of normal (gluten containing) bread or the equivalent per day, for two weeks before the endoscopy (compared with six weeks before a celiac blood test).  

Does eating gluten cause you a lot of symptoms?   If so, I quite understand that you would want  to give up eating gluten ASAP.   However,  sometimes people find that when they give up gluten their reaction to it can become more severe if they reintroduce it a few months later.   That is something you may wish to reflect upon, when deciding the timing of your endoscopy as you will need to be consuming gluten in the run up to the test.

Do you have the option of having a follow-up endoscopy quite quickly? As your doctor is recommending one, and if you feel able to do it, there is perhaps some merit in getting it out of the way so that you can get on with your gluten free diet without having to interrupt it for a gluten challenge prior to an endoscopy further down the line.

My apologies... I didn't read the last part of this sentence properly.   I see your problem... not knowing how long the wait will be makes it a bit more difficult to know what to do.  This is a problem that is besetting our healthcare system in the UK.  Can you get sort of approximate idea of how long the wait times are from your doctor?

It does look like from the number that you have celiac disease. Judging by the way you spelled "celiac" it doesn't look like you are in the UK.

Most definitely, you should be consuming a significant amount of gluten daily right up until the day of the endoscopy/biopsy. Your doctor gave you a bum steer by telling you to go gluten free.

What are your symptoms if any and how severe?

Hi! Thanks for your responses.

With COVID, all non-critical surgeries and some other procedures have been postponed here. With that, my best guess is that the wait-time could be months. I'll try to phone my doctor back to see if they have a better estimate.

Also, I wasn't aware that your symptoms might get worse after being off gluten for awhile! If that's the case, I might try to have the minimum required amount while starting a transition to an otherwise gluten-free diet.

Thank you for the help!!

Just to be clear, the symptoms don't get worse after being off gluten for a while unless you go back on gluten. What happens is you lose whatever tolerance you had before going gluten free.

Hi! Thanks for the reply.

My doctor informing me that I might have celiac's was quite surprising for me, considering that no one in my family has the disease (that I know of) and I didn't know much about it until a few days ago.

And you're right, I'm in Canada. Wait-times for medical procedures here are quite long right now, which is why I'm unsure about how long until I can get diagnosed.

My symptoms manifest in the form of stomach cramps and pain after eating gluten, bloating, gas, and other digestive problems. I also have iron-deficiency (which I take vitamins for) and skin problems. While these symptoms are manageable, they are quite annoying to deal with for an indefinite amount of time.

      @HectorConvector, Step off the gas. I'm in the U. S. That was what my doctor told me thirty years ago. Things may have changed since then. Things are different on the other side of the pond. Here we go by mg/dl. The smaller incremental changes are more noticeable using mg/dl. Also, I adopted a Ketogenic diet. Ketogenic diets don't spike...

      @knitty kitty Holy smokes, that Life Extension B-Complex is burning me up. My multi-vitamin already has 25mg of Niacin. The b-complex adds another 100mg on top of that. My face, neck, and ears look like the Cardinal I use for my profile pic. I have been on the b-complex for 10-days now and it seems to get a bit worse with each passing day. I think I...

      I'm not sure what you're referring to as "normal" here - and is this something your doctor has mentioned (in bold)? As that isn't what any study or official information says. According to diabetes UK and the British Heart Foundation, normal fasting blood sugar is 4.9-5.4mmol/L. Normal by 2 hours from the start of a meal is anywhere below 7.8mmol/L. Random...

      My skin biopsy and MRI scan shows no signs of any type of nerve damage. Nothing consistent with demylination or peripheral nerve damage. On the contrary, the nerve function from the skin biopsy proved better than normal. I don't get any pins and needles or have any loss of nerve function. It's pain only. Thiamin I take is 100mg a day in tablet. I...

      Terrible Neurological Symptoms

      By knitty kitty · Posted

      @HectorConvector, Step off the gas. I'm in the U. S.  That was what my doctor told me thirty years ago.  Things may have changed since then.  Things are different on the other side of the pond.  Here we go by mg/dl.  The smaller incremental changes are more noticeable using mg/dl.   Also, I adopted a Ketogenic diet.  Ketogenic diets don't spike blood glucose as much, and therefore return to fasting levels sooner.  My own experience is my postprandial blood glucose level returned to fasting levels an hour after the end of a meal on a Ketogenic diet.  I was asking if the thiamine you take is thiamine hydrochloride or Benfotiamine or Thiamine TTFD.  Thiamine Mononitrate is not well absorbed nor utilized by the body.  I learned that amounts larger than 100 mgs of thiamine hydrochloride needs to be taken in thiamine deficiency.   500mgs thiamine hydrochloride is recommended by the World Health Organization for several days and look for health improvement.  Thiamine is safe and nontoxic even in higher amounts. When thiamine is taken in high doses, there's a big change in energy availability, especially in the brain, where pain is registered.  A twenty percent increase in dietary thiamine results in an eighty percent increase in brain function.  Thiamine has analgesic properties.   I learned about high dose thiamine from Dr. Derek Lonsdale and Dr. Chandler Marrs through their website hormonesmatter.com.  I have taken high dose thiamine to correct my deficiency about fifteen years ago.  I could feel myself dying, I was so sick and in pain.  I was grasping at straws.  No harm, no foul, just to try it and see, right?  I tried it and that made all the difference.  High dose thiamine made astounding health improvements within a very short period of time for me.  I wonder if 500 mg of thiamine hydrochloride would have the same effect on you.

Have you noticed any side effects from that B-complex?  It is WAY over the daily recommended values: Thanks for your time, Known1

According to diabetes UK and the British Heart Foundation, normal fasting blood sugar is 4.9-5.4mmol/L. Normal by 2 hours from the start of a meal is anywhere below 7.8mmol/L. Random (more than 2 hours after a meal) should be below 5.6mmol/L.  Not in any study of normoglyceamic individuals does blood sugar go down to less than 5.4mmol/L one hour from the start of a meal, and I don't see such numbers being considered a limit for one hour post prandial in any official definition of normal blood sugar ranges anywhere. It is basically impossible even for the most metabolically healthy individual to have a blood sugar level anything like a fasting number 1 hour only after eating a high carb meal. This is also why medical standards use the 2-hour postprandial value, not 1 hour. Blood sugar normally spikes at about 1 hour after a high carb meal.  For example this study shows that young, healthy normoglycaemic people experience a 1hr peak blood sugar level of about 6.5-7mmol/L before which the 2hr number returns to about 4.7mmol/L, slightly higher than the fasting number of that morning. https://pmc.ncbi.nlm.nih.gov/articles/PMC2769652/?utm_source=chatgpt.com Even a normal person isn't going to be seeing essentially fasting blood sugar numbers after any meal except for one with 0 carbohdrates contents.

On the contrary, the nerve function from the skin biopsy proved better than normal. I don't get any pins and needles or have any loss of nerve function. It's pain only.  Thiamin I take is 100mg a day in tablet. I used to test blood sugar a lot in the past, and it never correlated directly with the nerve pain. It has only correlated with increased exercise and stress. The after eating getting worse thing happens when the blood flow is directed to the stomach for digestion away from the peripheral areas, which is normal, but central sensitization has caused normal sensations to be turned into pain by the brain, according to the latest doctors, hence whey I am being referred to the pain clinic.
