I have lots of gallstones, too! Guess we are part of a very large segment of the population of the world with the little darlings. Over 20 million stone-carriers in the U.S. alone! And over 500,000 GB removal surgeries per YEAR in the U.S., many of them with a not so happy ending like long term or life long digestive complaints like you've read about here.
About two months ago I had what is suspected to have been passage of a stone -- VERY painful abdomen, stabbing pains, for over two hours, but I held out and didn't go to the ER. It stopped, finally, with no other symptoms. Since then, I've had an ultrasound that revealed stones, and a basic HIDA scan. Yes, there are stones, but otherwise things appear normal.
GI doc is in a big hurry for me to have surgery; though he is NOT a surgeon. (Does he get a referral fee from a surgeon??) Like many, I fear surgery and even more-so because I nearly died from anesthesia after a hysterectomy many moons ago. But I digress...
Here's what we stone-carriers CAN easily do -- we can cut as much refined sugar as possible out of our diets. Ditto for starchy foods, fried foods, greasy foods, etc. No white breads of any kind. Cut way back on pasta, etc.
Drink chamomile tea, eat apples, eat carrots (the pectin is supposed to be good for the GB) and take Milk Thistle. Yes, it's an herb but it's been known to help liver/GB problems for 2000 years. Read up on it, it's all over the web. Milk Thistle gets high marks from just about everyone and is not known to have any bad side effects. Get enough Vitamin C, too. VERY important.
As a result of this "gall bladder diet," in six weeks I lost 10 pounds, feel much, much better, have had NO further complaints and the vague and annoying digestive upsets I'd been experiencing for six months prior to the "attack" are gone. Everything I learned was thanks to my local bookstore and the internet. No doctor will tell you anything other than "have tests and then have surgery."
Fortunately, my "family doc" agrees with me that surgery LATER, if I get really sick, is more appropriate than when just one or two incidents have taken place.
For the record, there are a lot of people out there with stones who only suffer occasional attacks and manage this as a "condition" rather than a crisis requiring surgery. Of course, if you are getting really sick very often, and your routine is constantly upset, by all means have surgery. Just my 2 cents. Best of luck to you -- and try the "gall bladder" diet. It's not bad at all and can't hurt you one bit.
