No, you don’t have an appendicitis. The piece of candy will have melted away long before it gets to the appendix. Appendicitis is not a chronic condition. If you have appendicitis, it progresses until it ruptures. If that happens, your symptoms would be so bad you would know you needed to go the hospital.

Celiac disease is an actual immune process with antibodies that react to the gluten protein. Gluten intolerance (like lactose intolerance) is not an immune process. The body just does not digest the protein well. Although intolerance causes symptoms from the undigested protein causing problem in the lower bowel, since there is no immune reaction there is no tissue damage or inflammation that occurs.

Not really. When your celiac disease is active, it wipes out your intestinal lining and can cause lactose intolerance because of that. That is temporary and on the diet the lining recovers and the enzymes come back. However, celiac disease is fairly common and lactose intolerance is very common. So, just by chance the odds stack up that some individuals are unlucky enough to have both.

Dairy products tend to be constipating. However, they are a great source of several nutrients that are low in other foods. The ideal diet is balanced with enough fruits and vegetables, which produce softer stools to counter balance the dairy intake. That is why the term used is a balanced diet. The appropriate diet would have the recommended amounts of dairy, but not too much with the other recommended foods in their recommended amounts.

What's the best way to stop my baby's diarrhea?

The BRAT diet has never been shown to improve diarrhea. In fact, some experts think it would be better to feed through diarrhea. I'm going to be blunt: we don't want to stop READ MORE
The BRAT diet has never been shown to improve diarrhea. In fact, some experts think it would be better to feed through diarrhea. I'm going to be blunt: we don't want to stop diarrhea. The body has diarrhea for a reason usually to clear an infection or a toxin. Diarrhea is good because it clears these out. If this is an infectious illness it can last several days and then should improve. Studies have shown that slowing down diarrhea actually prolongs the length of the infection.

Can dehydration be a cause of constipation?

Constipation is the result of lots of different factors. Part of it is taking enough water in to meet your bodies needs. The intestines will try to absorb as much water as possible READ MORE
Constipation is the result of lots of different factors. Part of it is taking enough water in to meet your bodies needs. The intestines will try to absorb as much water as possible if you take in enough and that leads to constipation. Food choices are also a big factor. Foods that are high in fiber (fruits and veggies) help keep some water in the intestines and result in softer stools.
