Any one become intolerant to owt later in life. I been getting bloated as f**k for bout a year . Started peppermint tabs and its sorted it but wondered if I.ve fell out with summet.
I.ve sacked bread of as well at same time .
Strange as I.ve allways been able to eat n drink what I want .
Also has anyone done the test that tells you if you are intolerant to owt
There are so many different possible causes of this, but one can be pancreatic insufficiency. If the pancreas becomes unable to secrete enough enzymes (various different ways this can happen), then food can fail to be digested fully and can ferment as it makes it's way further down the digestive system. Equally, if the stomach fails to produce enough pepsin or stomach acid something similar can occur. This can result in bloating, farting etc.
Interestingly, several organs contribute to the digestive process - the stomach, liver, gallbladder, pancreas, etc. and they all require certain minerals to function well. There are a few minerals which aren't very abundant in the modern diet, such as zinc, selenium, iodine, magnesium, etc. Additionally, certain heavy metals can actually interfere with the uptake and usage of some of these minerals, so, for some people, even if they have adequate dietary intake of healthy minerals, they may still have problems resulting from the inability of their organs to correctly absorb and use them. A classic example of this is mercury, which is toxic in many ways but one of them is that it can disrupt enzymatic pathways in the human liver, by interfering with the usage of zinc or selenium. These minerals are required to act as catalysts for enzymatic function, so if mercury disrupts this, then the liver can become unable to detoxify certain natural chemicals present in ordinary foods. This can cause countless health problems, but, in relation to digestion, one of the main ways that the liver eliminates some kinds of toxins from the body is by dumping the toxins into the digestive tract, within the bile (a fluid created by hepatocytes in the liver and concentrated in the gallbladder). If someone has a problem with heavy metals, then it can sometimes result in a situation where the liver is unable to detoxify some chemicals which a normal healthy liver would be able to detoxify using enzymatic reactions. If, then, the liver is forced to dump a wider range of toxins into the digestive tract, via the bile, then this can potentially cause the delicate cells that line the intestines or bowel to react and become inflamed. Similar inflammation can also be caused by inadequately digested food particles (in patients whose stomach or pancreas aren't functioning well, for example). This is because the digestive system has a huge interaction with the human immune system.
If you ever delve into the human digestive system (as I had to, when I suffered issues, a few years ago), you may quickly realise it is very complex and there are so many different ways digestion and digestive organs can be impaired. If you are genuinely serious about wanting to find out what may be going on in your own case, John, then you could consider getting private lab-testing done (proper testing, through a qualified practitioner, not mickey-mouse tests), but it costs a few hundred quid per test and it only gets you part of the way towards finding out what the root cause may be. One of the things such testing can measure is how well your pancreas is producing enzymes, or if there are any parasites causing an issue.
Not trying to bore you or show off knowing something - I only learned the above because I had issues with my own digestion, and, as I said, the topic of human digestion is a very big and very complex one, which I only know a tiny fragment of.
At the very least, you might consider trying a digestive enzyme supplement. It can be very effective to keep a food diary - very boring but can sometimes help you figure out if certain foods are causing the worst of your symptoms, and that can help you narrow down what might be actually happening in your body. For example, a lot of people don't tolerate lactose well, but don't even realise it. There have been periods in my life when I have experienced quite unpleasant 'burning' sensations in my left side when I have eaten tomatoes or eggs, but I didn't twig that there was a relationship between eating these foods and experiencing the sensations a few hours later, until I made the effort to keep a food diary, and noticed a pattern in it.
Also, try to avoid using antacids on a regular basis, if you happen to be someone who does this - if you keep neutralising the acid your stomach is trying to produce, then this may cause problems further down the digestive tract, over the longer term.
Lastly, try to make an effort to get a decent mineral intake in your diet. I would prefer to get all my minerals from my diet, and not use any supplements, but I have to admit that it can be difficult to find enough magnesium and zinc in a normal diet, these days.
Apologies to everyone else for the longwinded essay, but a sincere question deserves a sincere answer.
