I eat so little, but still I feel heavy. Is there a problem with my digestive system?

Maybe, but the symptoms are a bit vague and thus it's tough to make any conclusions with so little information. Bloating is usually due to carbohydrate malabsorption so you might READ MORE
Maybe, but the symptoms are a bit vague and thus it's tough to make any conclusions with so little information. Bloating is usually due to carbohydrate malabsorption so you might consider reducing carbs in your diet. This usually help reduce bloating. A visit to your primary care doctor or a GI doctor will help make sure nothing else is going on.

My upper abdomen is bloated because of gas. What should I do?

It may not actually be gas. Most people with bloating think that gas is causing the problem but it's usually not gas accumulation. Rather it is often fluid accumulation in the READ MORE
It may not actually be gas. Most people with bloating think that gas is causing the problem but it's usually not gas accumulation. Rather it is often fluid accumulation in the small intestine due to ingested carbohydrates that are not well digested. My first recommendation is to lower the carbohydrates in the diet. That will help in many cases. Otherwise, consider seeing a GI doctor to get a proper evaluation, especially if other symptoms are present, such as vomiting, pain, weight loss or anemia.

Is Crohn's disease a hereditary disease?

There is some genetic risk for Crohn's disease, so yes, your son will have an above-average risk for also getting Crohn's, but the absolute risk for him is still fairly low. There READ MORE
There is some genetic risk for Crohn's disease, so yes, your son will have an above-average risk for also getting Crohn's, but the absolute risk for him is still fairly low. There are no ways to test for the genetic risk. You only need to simply observe him for symptoms. IBD can present at any age, but often does so in adolescence or early adulthood. Avoid all
unnecessary antibiotic exposure, especially in early years of life. Avoid exposure to cigarette smoke. Hopefully your son will never develop IBD.
Good luck.

Do I need another endoscopy?

No, it doesn't sound like another endoscopy would be helpful. First, you probably had a regular upper endoscopy (EGD) and not an endoscopic ultrasound. The latter is used to visualize READ MORE
No, it doesn't sound like another endoscopy would be helpful. First, you probably had a regular upper endoscopy (EGD) and not an endoscopic ultrasound. The latter is used to visualize structures outside the walls of the stomach and duodenum and it doesn't sound like you had something like that.

Acid reflux should be fairly easily treated with anti acid pills like Protonix. Lack of improvement can be evaluated further, but should be discussed in clinic. Abdominal pain is more elusive and could be from H. pylori infection or more often dyspepsia or hypersensitivity. A simple follow-up with your GI doc should suffice for now.

Is there a cure for IBS?

There is no cure for IBS, but none of the medications that you listed are treatments for IBS, meaning irritable bowel syndrome. I would advise you to make sure that a proper diagnosis READ MORE
There is no cure for IBS, but none of the medications that you listed are treatments for IBS, meaning irritable bowel syndrome. I would advise you to make sure that a proper diagnosis is made and that appropriate therapy is given. See a GI physician, and if you have already seen one, then you can seek a second opinion.

Loss of appetite and nausea

No, I don't think it is normal to have problems with nausea after eating more than 1 year after that surgery. The nausea may have started as a result of everything that you went through, READ MORE
No, I don't think it is normal to have problems with nausea after eating more than 1 year after that surgery. The nausea may have started as a result of everything that you went
through, but now the nausea is its own separate problem. We often call this functional nausea and it can be treated with medications. An evaluation by a GI doctor is reasonable to make sure it is not something else.

Anal fissure

That's a long time to be having symptoms from an anal fissure. Assuming that you have been treated in the usual manner with nitroglyercine ointment four times per day, laxatives, READ MORE
That's a long time to be having symptoms from an anal fissure. Assuming that you have been treated in the usual manner with nitroglyercine ointment four times per day, laxatives, etc., and assuming that this medical treatment did not work, then surgery can be appropriate for a non-healing anal fissure. Nothing is 100%, but relief from surgery is a likely outcome and I would refer to surgery if a fissure is not healing after medical treatment.

After colonoscopy

The doctor who performed the colonoscopy should be able to confirm that the bleeding is from hemorrhoids and nothing else. If the cause of bleeding is hemorrhoids and you wish READ MORE
The doctor who performed the colonoscopy should be able to confirm that the bleeding is from hemorrhoids and nothing else. If the cause of bleeding is hemorrhoids and you wish to have this addressed, then potential treatments include hemorrhoid banding or surgical hemorrhoidectomy. Again, whomever performed the procedure may be able to offer these treatments so I would start by contacting that physician. If he/she cannot help with hemorrhoids then you may need to seek advice from another doctor who does.

Best of luck.

Crohn's disease and Lupus

It's not common for lupus and Crohn's to co-exist but anything is possible. More likely are lupus-like syndromes that can occur with certain treatments for Crohn's disease. Patients READ MORE
It's not common for lupus and Crohn's to co-exist but anything is possible. More likely are lupus-like syndromes that can occur with certain treatments for Crohn's disease. Patients would need to see a rheumatologist to help sort things out if lupus is suspected. It all depends on the specific symptoms and the history. Diagnosis is by clinical picture and blood tests ordered by the rheumatology doctor.

Hope this helps.

I have Celiac disease. I was diagnosed appx. 15 years ago.

First, we must be careful with the diagnosis of celiac. It is often misdiagnosed. If you came to see me as a patient, I would first get documents of the prior work up to convince READ MORE
First, we must be careful with the diagnosis of celiac. It is often misdiagnosed. If you came to see me as a patient, I would first get documents of the prior work up to convince myself that the celiac diagnosis is correct. If the celiac diagnosis is true and accurate, then persistent symptoms on a gluten-free diet generally have 2 main explanations:

1) You are exquisitely sensitive to gluten and it is getting into your diet surreptitiously. It does this via food ingested, not due to utensils used, so I don't think you need to change the cutlery that you use to eat with.
2) The symptoms are not due to gluten at all but rather another condition may be at play. Typically nonulcer dyspepsia or visceral hypersensitivity, which is very common in the setting of fibromyalgia, are high on the list of possibilities.

A GI doctor can help sort this out.
Good luck.

Light brown

It's normal for the stool to vary in color depending on your diet. Light brown is normal and nothing to be concerned about.

Eating habits

I will assume that you really have celiac disease, which is often mistakenly diagnosed. If you are avoiding all gluten, then the pain you have is unrelated to celiac and it is READ MORE
I will assume that you really have celiac disease, which is often mistakenly diagnosed. If you are avoiding all gluten, then the pain you have is unrelated to celiac and it is certainly also unrelated to absence of a gallbladder.

There is probably another source for pain such as gastritis or dyspepsia. The latter is very common and just means you have a sensitive stomach that reacts sometimes to anything ingested. You might be sensitive to or maldigesting sugars in fruits. Some tests by a GI doctor could help identify one of the above causes.

What could be the reason for my stomach bloating?

Most benign bloating that happens daily and chronically after eating a meal is due to carbohydrate malabsorption. Lowering carbs in the diet usually helps. If you have tenderness, READ MORE
Most benign bloating that happens daily and chronically after eating a meal is due to carbohydrate malabsorption. Lowering carbs in the diet usually helps. If you have tenderness, then it could be something else and an exam by your primary care doctor or a GI doctor would be advised.

After a colonoscopy is soft rust colored stool normal?

Yes, this is normal. The stool will tend to be soft since you just had an oral clean out of the colon. The rust color may be some minimal blood from a biopsy or polyp removal that READ MORE
Yes, this is normal. The stool will tend to be soft since you just had an oral clean out of the colon. The rust color may be some minimal blood from a biopsy or polyp removal that would typically be done during colonoscopy.

help for excessive IBS diarrhea pain

You need to be properly treated for IBS. You have a prominent gastrocolic reflex causing diarrhea after eating. There is treatment available and you should go back to your GI doctor READ MORE
You need to be properly treated for IBS. You have a prominent gastrocolic reflex causing diarrhea after eating. There is treatment available and you should go back to your GI doctor and insist on being treated. If the GI doctor refuses to do anything or doesn't offer anything useful, then find one that will. The sad reality is that a lot of GI docs don't want to be bothered to treat IBS. Don't give up.

REMICADE and weight gain

Patients with Crohn's and UC usually lose weight due to active disease. When they get treatment that reduces the inflammation of the bowel, nearly all patients gain weight. Thus READ MORE
Patients with Crohn's and UC usually lose weight due to active disease. When they get treatment that reduces the inflammation of the bowel, nearly all patients gain weight. Thus it would not be surprising to gain weight after starting Remicade, assuming that it was successful in treating the IBD. Weight gain alone is not a side effect of Remicade, but rather a
consequence of its success.

Can you suggest some safe medication to treat heartburn?

Any antacid med can treat heartburn: over-the-counter Zantac, Prilosec, Nexium, or prescription versions of these pills. All are safe, but use the lowest effective dose. Otherwise, READ MORE
Any antacid med can treat heartburn: over-the-counter Zantac, Prilosec, Nexium, or prescription versions of these pills. All are safe, but use the lowest effective dose. Otherwise, can consider GI workup with EGD if not done previously. Surgery to control heartburn is another option.

Are fruits like watermelon and pineapple okay for people suffering from acid reflux?

Yes, it's okay to eat those fruits and others. Won't affect the heartburn significantly.

Does excess protein intake cause acidity?

The amount of acid made is fairly steady from day to day, and it normally increases when a meal is eaten. If you experience more heartburn, this doesn't mean that you are making READ MORE
The amount of acid made is fairly steady from day to day, and it normally increases when a meal is eaten. If you experience more heartburn, this doesn't mean that you are making more acid than usual. It means that the acid being made is going where it shouldn't (i.e., into the esophagus). In general, to reduce acid reflux, eat lighter meals, avoid overeating, don't lie down soon after eating, avoid caffeine, alcohol. There are many factors that can cause more heartburn, but protein-rich foods are not a significant cause. Use pepcid or nexium pills if heartburn is bothering you a lot. If it becomes a chronic issue, then it may help to see a GI doctor.
