Low stomach acid ???

2 Upvotes

I suddenly developed constipation 5 months after contracting ghsv1 and after a 2 week alchohol binge and it hasn’t gotten better since. I feel like my food just sits in my stomach , I don’t have a urge to poop but when I do poop it’s soft loose stools . I burp all day and have really smelly gas . When I do an enema there’s barely anything that comes out , laxatives rarely work. I noticed there’s undigested food in my stool and sometimes my stool is green . I got a colonoscopy and my colon is fine they say. I’ve been doing research I know about sibo etc, which I’m sure could be a factor. All the doctors wanna do I put me on miralax and linzess which doesn’t work .

Advice Wanted White specks in stool

1 Upvotes

12 days ago i had food poisoning from raw milk (i believe i got campylobacter if i remember correctly what the doctor said)

i had fever first 2 days then bloody diarrhea for a few days once the fever passed

my stool color turned normal but i had stomach cramps while pooping up to like day 9

doctor only prescribed me with a stomach relaxer

the only symptoms i have left now is white specks in my stool and an ithcy anus from time to time

im paranoid this could be the start of an autoimmune / chronic disease and that my symptoms might show up again since reading that food poisoning can be the start of life long digestive diseases

Somatropin HGH - gut studies

0 Upvotes

So I got banned for posting a question about this subject (title) by a mod that said that I had no right to post about something that is completely experimental, dangerous and something about blackmarket drugs ( I did not mention anything on this matter). I received 3 total replies before being banned and here is the reply for those who are more interested; Yes there is science to back this up. Here are some articles to prove it.

Study description:

  1. Small Intestine:

Intestinal Ion Transport: A study published in Pediatric Research examined the acute administration of hGH on rat ileum. The results indicated that hGH rapidly increased the absorption rates of water, sodium, chloride, and potassium. In vitro experiments showed that hGH decreased transepithelial potential difference and short-circuit current, suggesting an inhibition of basal active chloride secretion. These findings suggest that hGH has a direct antisecretory effect on the intestine, enhancing its absorptive function.

Mucosal Growth and Proliferation: Research published in Gut explored the trophic actions of hGH, insulin-like growth factor-I (IGF-I), and insulin on human duodenal mucosa cultured in vitro. The study found that all three hormones significantly increased crypt epithelial cell proliferation, with IGF-I being the most potent. This indicates that hGH and its mediators play a role in regulating cell proliferation in the human small intestine.

Intestinal Barrier Function in Sepsis: A study in the Brazilian Journal of Medical and Biological Research investigated the effects of recombinant human growth hormone (rhGH) on the intestinal mucosa barrier in septic rats. The results demonstrated that rhGH attenuated intestinal mucosal injuries and bacterial translocation. Additionally, rhGH influenced the expression of proteins related to apoptosis, suggesting a protective role in maintaining intestinal integrity during sepsis.

Post-Trauma Intestinal Homeostasis: Research in PubMed assessed the impact of growth hormone on gut mucosal homeostasis after severe trauma. The study found that while hGH did not significantly affect small bowel epithelial cell apoptosis or proliferation, it improved villous morphology, indicating a role in maintaining intestinal structure post-injury.

  1. Pancreas:

While the provided studies primarily focus on the intestines, research indicates that hGH can influence pancreatic function. hGH has been shown to induce insulin resistance in peripheral tissues, prompting the pancreas to increase insulin secretion to maintain glucose homeostasis. Over time, this increased demand may stress pancreatic β-cells.

  1. Colon:

Specific studies directly examining the effects of hGH on the colon are limited. However, the general trophic effects of hGH on intestinal mucosa suggest potential influences on colonic tissues, warranting further investigation.

Antinutrients free Oat alternative

0 Upvotes

Hello everyone,

Does anyone know of an antinutrient-free oat alternative?

Due to intestinal problems and food allergies,

I'm currently switching my diet to only natural foods.

I used to eat oatmeal with yogurt, wild blueberries, and honey, but the antinutrients in oatmeal are causing me major problems (gluten isn't a problem for me).

I'm happy to hear any suggestions.

I’ve started a one week course of amoxicillin and am 4 days in. 500mg three times a day. It just started today but I get whiffs of smoke/campfire that no else seems to smell. Has anyone else experienced random smells when on amoxicillin. Of course google says brain tumor so that didn’t help.

Custom probiotics d lactate free - success timeline?

4 Upvotes

I’ve recently got rid of sibo (thank god).

Now is time for me to fix my histamine intolerance. For those who had success with custom probiotics D lactate free or a similar probiotic, what sort of timeline did you have for fixing histamine intolerance?

I’ve started cautiously (1/8th baby scoop), only 2 days in and have had some increased histamine response, which is annoying but I’m not concerned about. Particularly not concerned because 1/8th baby scoop when I had sibo sent me insane and didn’t let me sleep for days, whereas I can sleep after taking the custom probiotics now.

Overall, what sort of thing should I be expecting, how long did it take to help you?

Desperate for help.

8 Upvotes

Hello everyone. I'm in desperate need for help and I have been for too long now. I believe there's something really wrong in my stomach, and I'm just barely staying alive right now. I'm trying to help myself by figuring out what is wrong with me. My doctor doesn't believe me - she's called my issues psychological for over 6 months now. I have to save myself somehow. Will list symptoms and if anyone had any guidance or ideas about what's going on with me I'll be forever grateful. 😓

I'm a 37 year old female. Previously very healthy and active. 6 months ago I got a pneumonia and insane symptoms have since followed. I now have suspected Pots, a small hiatal hernia and esophagitis.

SYMPTOMS:

  • Neurological issues when I swallow anything (skin burning/stinging)
  • Overheat when eating ANYTHING
  • Joint and bone pain
  • Episodes where I wake up and my skin has become dry and flaky over night, and I pee like crazy
  • Very upset stomach, always runny or constipated
  • Stomach burns like fire near the ribs when I eat
  • Tight throat
  • Migraines from hell
  • Swollen and red tonsils and sometimes swollen/white tongue but negative for candida several times.
  • Periodically extreme fatigue
  • Have had hypokalemia 5 times during these 6 months
  • I'm either freezing or boiling up, seem intolerant to temperature changes
  • Low grade fevers randomly
  • Random anxiety attacks for no reason
  • Acne prone
  • Sometimes it burns when I pee when I'm in a flare but no UTI or STD etc.

My very first symptoms started in my stomach, and it feels like something is very wrong there. I've had upper endoscopy but they couldn't do a biopsy because the air they blow in just shot straight out of me and I was throwing up loads.

THINGS I'VE DONE MYSELF:

  • Tried elimination diet but nothing helps
  • Tried to stay hydrated with fizzy tablets
  • Gone to several different doctors and had overnight stays at hospital for potassium IV.
  • Tried low histamine diet ( no difference )
  • Tried taking antihistamines and pepcid ( since many people have previously mentioned MCAS but no difference)
  • Tried water fasting which helped symptoms after 4 days but only for a few days until I flared again.
  • Scheduled an endoscopy to check bowels
  • Scheduled at cardio for Pots

If anyone has any idea or recognises symptoms, please share anything and everything you can. This is intolerable, I'm barely functional at this point and the neurological pain hurts so so bad. I'm helpless and I live in Sweden so the doctor's here don't test for things like Sibo or leaky gut. I need all the help I can get. 🌷 I don't want to live in my own body anymore.

Advice Wanted Bad breath - what is the cause? how to fix it?

15 Upvotes

I have always had bad breath.

I have visited dentists, ENT specialists and gastroenterologists. Dentists and ENT specialists have ruled out complications. So it is presumed to be a gastroenterological problem.

My symptoms are: bad breath, slightly white tongue (it is not candida according to the ENT specialist).
It seems to me that bad breath gets worse during the digestive phases.

I have impeccable oral hygiene. Dental floss, I go to the dental hygienist every six months, waterpick, I brush my tongue etc.

What tests have I done: Helicobacter pylori test, SIBO test, abdominal ultrasound, blood tests, stool tests, food intolerances, lactose test, celiac disease test, stomach acidity test, ENT specialist ruled out the presence of tonsil stones.

These tests only revealed a dysbiosis that I have healed.

What I tried: no carb diet, no dairy diet, took enzymes, ppi, nasal washes, motility medications, castile soap.

The situation is slightly improved but not cured.

What is left for me to try?

What could be the cause?

Fulvic acid side effect

0 Upvotes

Can anyone relate or is it all in my head. I took fulvic acid a few months to help with digestive health but I think it affected my vision. The world around me seems cloudy and not real. When I google the symptoms derealization comes up but I’ve never had an issue with anxiety or depression. The world looks different now, feels like I’m in a dream. So far I haven’t spoken to anyone who had similar side effects. My optometrist said my vision was still perfect
