I don't think there is a certain pH level that causes indigestion,
although the higher the acidity, the greater the potential for problems.
However, indigestion can be a result of too low of a pH. When food enters
the stomach and enzymes are released, the pH can become very acidic (pH
around 2) so that it can break down the complex food molecules, like
carbohydrates and proteins. When one has indigestion caused by stomach
problems, it may be indicate a more severe underlying disorder like
eusophygeal reflux disease in which acidic stomach contents "burn" the
eusophagus. This can cause severe heartburn. Many people suffer
heartburn, which is usually caused by the eusophygeal sphincter not closing
all the way, or simply from eating a really spicy meal. Some people who
may have underlying heart disease, may mistaken heart pains or myocardial
infarctions as heartburn. Some people suffer indigestion due to ulcers in
the stomach. Some ulcers perforate and can cause bleeding into the
peritoneum, which is a much more serious problem. There are people
who have bled to death from such severe ulcers. Usually there is severe
pain associated with severe stomach ulcers.
Some indigestion can also be caused by the abnormal closing or
function of the duodenal sphincter, which is responsible for emptying the
stomach contents into the duodenum (first part of small intestines). In
the duodenum, other enzymes are added and digestion and absorption take
place. As you probably already know, these sphincter muscles located
throughout the alimentary canal are controlled by smooth muscles, muscles
in which we have no voluntary control. They are under parasympathetic
control of our nervous system. Other indigestion can be caused by lack of
the body to digest certain foods, like milk products or beans. This leads
to abdominal discomfort or cramping. There are other problems associated
with long term indigestion, like irritable bowel syndrome, or coilitis.
Anyway, I hope the above information helps. Good luck to you.
