Hey @Sue777
So I’ve been researching this a bit more and have found a passage relating to Dumping Syndrome explaining the 2 different types “early dumping” and “late dumping” and for ME this is ringing a LOT of bells right now.
I’ll copy and paste (this is from the Wikipedia page for Dumping Syndrome - which is not just related to gastric surgery, as is often said.)
Dumping syndrome has two forms, based on when symptoms occur.
Early dumping syndrome occurs 10 to 30 minutes after a meal.
It results from rapid movement of fluid into the intestine following a sudden addition of a large amount of food from the stomach. The small intestine expands rapidly due to the presence of hypertonic/hyperosmolar contents from the stomach, especially sweet foods. This causes symptoms due to the shift of fluid into the intestinal lumen, with plasma volume contraction and acute intestinal distention. Osmotic diarrhea, distension of the small bowel leading to crampy abdominal pain, and reduced blood volume can result.
Edit: This can lead to sudden drops in blood pressure and even Hyperosmolar syndrome.
Late dumping syndrome occurs 2 to 3 hours after a meal.
It results from excessive movement of sugar into the intestine, which raises the body’s blood glucose level and causes the pancreas to increase its release of the hormone insulin. The increased release of insulin causes a rapid drop in blood glucose levels, a condition known as alimentary hypoglycemia, or low blood sugar.
Edit: Low blood sugar having the usual typical symptoms of shakiness, anxiety, nervousness, palpitations, tachycardia, sweating, feeling of warmth, pallor, coldness, clamminess, hunger, nausea, vomiting, abdominal discomfort, headach, etc.
So for me, this is ringing a LOT of bells.
I think I get both of these.
They are not really “spectacular” (I think “dumping syndrome” sounds really extreme) they just feel like bowel movements that don’t feel quite right and seeing as I’ve had IBS for 20 years, I’ve just gotten used to this.
What I didn’t realise is the osmotic stuff going on (water being surged out of your bloodstream into your intestines and I assume all kinds of electrolyte madness!!) or the weird effects it was having on blood sugar.
I’ve had these feelings of exhaustion/ dizziness/ low blood pressure/ all the symptoms of low blood sugar etc regularly and never thought they could be related to my IBS!!!
I thought the low blood sugar stuff MUST be related to blood sugar/ insulin/ diabetes type stuff, cos DUH where else would it come from??
I seriously need to make an appointment with my gastro-enterologist!!
Can’t believe he never told me about this after 20 years of IBS, tons of testing for food intolerances, abdominal migraines, etc etc etc.
It takes ages to get a specialist Dr’s appt here, so it’ll be a while til I can report back on the doctor’s comments but I am going to see if I can research this some more and maybe get a book about it on Amazon.
