Hi Carol,
It's good to see you posting again, but I'm sorry to hear of the new problem.
Actually, gastritis can be caused by many things, one of which is bacteria, and H. pylori is indeed the most common type of bacteria to cause gastritis, so your doctor is on the ball to check that out as a possibility. The results of the examination of the biopsy samples should give you an answer to the question of whether or not H. pylori is the problem. If the results are negative, though, then you are going to have to look elsewhere for the problem.
Your doctor is probably never going to think of this, and he will probably laugh at the idea, if you suggest it, but your gastritis could be due to the Asacol that you're taking. Here's why:
One of the most common causes of gastritis is aspirin. Aspirin is salicylic acid. Asacol is Mesalamine, and mesalamine is a derivative of salicylic acid. It could, therefore, be the cause of your gastritis, and this should be checked out. Most doctors consider Asacol to be a very safe medication, but the fact of the matter is that it has been connected with some very serious GI issues. For example, for some individuals, especially those who have been using Asacol for long periods of time, Asacol has been shown to cause chronic pancreatitis, which is a very serious condition, and many doctors are not even aware of this risk.
Certain supplements can cause gastritis for some individuals, such as iron tablets, or potassium supplements. If you are taking any of those, they could possibly be the cause of the problem, or a part of the cause.
Also, be aware that gastritis can be due to autoimmune causes, and anyone with MC is vulnerable to additional autoimmune issues. Gastritis can even be due to the same pattern of inflammation that causes MC. Does that make it a part of MC? Technically no, because of the way that MC is named, (colitis can only refer to the colon), but the fact of the matter is that the same type of inflammation that cause the symptoms of MC, can also be found in the small intestine, and even the stomach, for some of us.
Note that most "mature" people with chronic gastritis, tend to develop a deficiency of vitamin B-12, which can cause increasing weakness, loss of memory, and depression, so please be sure that you take some extra B-12. You can't take too much B-12, so don't worry about an overdose. Also, be sure you take the sublingual form, (the tablets are designed to be dissolved under the tongue, and the directions on the label should state that).
I hope you can find the cause, and get it corrected soon. It's a heck of a note that you have to continue to suffer for another five weeks, while you're waiting for the next appointment. The way the medical establishment operates, seems to be kind of cruel, sometimes, IMO.
Love,
Tex
