From the NOLA 09 Conference - Leigh Ann Burns, MS, LDN/RD, CNSDOncology Nutritionist/LSU Cancer Prevention
She’s been a nutrition consultant for more than 20 years. In her opinon, carcinoid is different from other kinds of cancer, especially when it comes to the Big D – diarrhea – which most of us deal with.
Burns says consider where tumor bulk is (foregut, midgut, hindgut, etc.) and your specific symptoms, whether they are diarrhea, skin problems, wheezing or joint pain.
Keep a food and symptom diary for a while before consulting a dietician. They always wonder about what goes in and how it comes out.
Diarrhea – Basic Mechanics*
Osmotiory - how much water passes through the gut membrane.
*
Secretroy - what is being secreted by the tumor that makes diarrhea happen.
*
Decreased contact time and surface - short gut, motility.
Probably a combination of all these factors can cause diarrhea. Sometimes the intestinal tract has been flattened by decreased contact time so the process of digestion gets slower.
Many times all three conditions contribute.
Osmotic – absorption of nutrients may be hampered by:
* lactose intolerance
* tube feeding
* sorbitol and manitol – these artificial sweeteners often are in diabetic foods and are known to cause diarrhea.
* epsom salts, used to prep for surgery
* antacids – especially if over used. Many are magnesium based and may also be in GI prep for surgery.
Quit giving/taking these things and sometimes you can stop osmotic diarrhea.
Secretory diarrhea is harder to stop. Intestinal water exceeds absorption before it leaves the colon. Causes watery stool.
Bacterial toxins are present whether you’ve eaten or not. Must test PH of stomach and it can show if you have this.
Drugs may also cause it, especially those for asthma, antidepressants and cardiac meds.
Other causes for diarrhea – heavy metals, organic toxins, accidentally ingested mushroom toxins and caffeine with or without sugary snacks.
Secretory diarhhea especially characteristic of:VIP vasoactive intestinal peptide
Midgut due to gastrin and other markers
Short bowel if you’ve been resected
Inflammatory bowel (probably your dx before the correct one)
Gluten intolerance (also known celiac sprue) symptoms also shared by NETs
Pancreatic insufficiency for whatever reason – can be due to tumor or partial removal.
Intestinal surgery – may cause narrowing of the gut, short gut
Gallbladder removal – things are never the same, afterwar
Bacterial overgrowth – this condition often is underestimated
Bile acid - related colitis
Drug induced (somatistatin analogs)Burns spends most of her time dealing with this aspect of diarrhea.
Intake refers to carbs, proteins and fats. There may be too much of one or they may not be digested properly. Outgo is formed stools vs. runny stools, dark brown vs pale colored or fatty stools that float. A strong odor is associated with carcinoid stools. (understatment!)
Very few pts Burns sees have a normal gastro-intestinal tract.
Digestion starts much sooner than you think. It actually begins when you see and smell food, which causes acid to form in stomach and saliva in the mouth. Some digestion occurs in the mouth when you chew the food.
When we take out the gallbladder, we’re going to have seepage of bile into the small intestine. Same with the pancreas. If we stop the normal release of enzymes, we will see reduced enzymes in small intestine. This will affect how food broken down.
Meats need more acid. So when there’s not enough acid in the stomach, digestion is slowed in the stomach. By the time food gets to the ileum, it’s best to have all the bile acids absorbed. otherwise bile may enter the cecum, causing damage to large intestine. This is what causes lots of diarrhea in many cases.
You need to know the transit time. It should take at least 30-50 minutes after eating for stool to form.
Some tips for decreasing those smelly floatiesIf possible, eliminate caffeine or anything that stimulates GI tract, thus affecting absorption. Headache remedies and other OTC meds can be a problem. Try to use the smallest amount possible and stay close to home. If you must be outside of a controlled situation (travel?) it might be best to avoid the medication altogether.
Cut down on fructose and sucrose, sweeteners found in apple, pear, soft drinks, even sugar-free and milk products. Yoghurt and “cured” milk products are not as bad. Increased motility is caused by activity, stress, foods like concentrated sweets, mix of solids and liquids, extreme hot and cold, fiber types. Increased motility equals diarrhea for most folks.
What can you take for diarrhea?Anti-diarrhea meds work by slowing down the GI tract to improve water absorption. Immodium, codiene and opium, cholestyramine, pancreatic enzymes, probiotics, all are possible medications to decrease the amount of water flowing to quickly into the colon.
All work in some cases but they only treat symptoms and not the underlying cause of diarrhea.
A “dumping syndrome” diet can be used for short or long time.
Cholestyramine – is prescribed when bile salts may be problem. It also has cholesterol-lowering properties. Cholestyramine can carry bile salts out of the tract before food reaches colon. Beware - if you are taking cholesterol-lowering drugs, you might have to separate the two medications at least by at least two hours or more to avoid interference.
Why steatorrhea?AKA “the floaties” – large volumes of foul-smelling, greasy stools. Often pale.
They indicate you are not getting enough lipase to break down the amount of fat you’re taking in. You need additional enzymes to aid in digesting fat. Eat less fat.
Protein is one of the harder energy sources to break down. Many ‘noids take pancreatic enzymes when they eat – a meal or even a snack. Since folks with carcinoid need more frequent meals, they need to take the enzymes more often.
Generic pancreatic enzymes were taken off the market because they don’t cross over for use in the body. Burns does not give out prescription versions of generic pancreatic enzymes. Be aware that sometimes products change over time.
Top tip for cutting down on fat: use a smaller plate. Probiotics- these substances restore natural flora in the gut. Unfortunately, they may increase the amount of gas but help lessen diarrhea. Bacterial overgrowth can occur with the syndrome. Probiotics and Flagyl works.
The biggest problem with diarrhea is not the embarrassment, or even the physical discomfort.
It is the chronic loss of nutrition. Supplement your diet with proteins and carbs, both of them may be given in powder form. Sometimes it helps to eat solid food first, with no liquid. Then drink your liquid 30 to 45 minutes later.
Q: How does sugar affect liver? A: Probably sugar is related to malabsoprtion, rather than tumor growth. Sugar does not necessarily promote tumor growth. Anytime your body releases high levels of insulin, you also release insulin growth factor (IGF) which is one of the biomarkers that may affect NETs but there’s no conclusive evidence now that IGF is linked to tumor growth.
Q: Is Aspartame harmful?A: Aspartame is being researched. High amounts appear to be harmful to some. One packet may not be but a current study shows MS may be adversely affected. Aspartame can cause diarrhea but it’s not as bad as sorbitol.
Q: Could you take probiotics forever? A: Yes, they have very little potential harm.
Q: Anal problems such as itching, burning. What causes this?A: Usually from faulty bile salt absorption. Cholestyramine can be useful. If the itching is from leakage or seepage of stool, you may have to change the PH of the bowel.
Stay hydrated – noids need more water than they usually drink and you need to offset the loss of water from diarrhea.Labels: NOLA Conference 2009
