Sounds like a dairy or gluten problem. Very possible your husband could be having some symptoms of Celiac. (information can be found at http://digestive.niddk.nih.gov/ddiseases/pubs/celiac/#1
But the real underlying problem to most if not all of his problems is very likely CANDIDA ALBIKANS or CANDIDASIS
Sounds like somebody took quotes of my life and the problems I suffered for the first 50 years of my life. I was at my final point of all these problems and more on 13 medications.
I am now and have been for 7 months medication free (including over the counter) and as long as I am careful not to eat foods that are ridiculous I am completely symptom fee....and have lost 72 lbs!!!
I tell you this so you will know that what I am about to tell you will be received with more confidence. This will not only solve the "gravy" problem but the heartburn, anxiety, blood pressure, cholesterol, weight and other problems your husband is having....not to mention saving your hundreds of dollars a month.
YEAST overgrowth!! Yeast is fungus and fungus is the culprit for most disease in the body. It begins in the GUT! the intestinal tract and then is distributed to the rest of the body through the bloodstream. The "medical" term for this overgrowth (which every human being has to a certain extent is CANDIDA ALBIKANS
Lipitor, Zocor...and other statin drugs are derived from ANTIFUNGALS
!! Then all kinds of other "chemicals" additives are added and POOF! you have a medication that costs an arm and a leg ...and your overall health!
PEPCID and other antacids work to alkalinize the stomachs acids. Acids are what we produce to break down the food. Adding an alkaline (such as an antacid) is encouraging the body to work "against" itself and increasing the problem. The fungus in the digestive tract will increase heartburn.
I took Zoloft, Alprazolam, anti-psychotics for Depression, pain, IBS, anxiety for 13 years and gained 100 lbs still suffering when I finally stopped all the medications...in fact was literally hours from death when I finally figured out as one sypmtom led to another....so went the medications...causing more side symptoms and so on!
There is information all over the internet regarding Candida and how has been proven to be the underlying cause to so may diseases (including MANY terminal diseases. there are many many recommendations for Candida diets and products for cleanses of Candida which will then rid the overgrowth and clear up many of the symptoms your husband suffers.....and make your life a bit happier too! My husband suffered "with" me all these years and it's so nice to see him happy again! As you cleanse the body of the "bad" bacteria caused by the yeast/fungal overgrowth it will be necessary to be replacing with "pro" flora/bacteria using an acidopholis or more widely known now as "probiotic"
Sorry this was so long, but, going from literally death 13 months ago to a doctor's report of "optimum health" 2 weeks ago impells me to share just the tip of the iceberg to good health and enjoying living again..Doc wanted to know what I did...as I was also diagnosed and treated for emphysema last year and there is absolutely no sign whatsoever of emphysema in my lungs now! Again, sorry this is long, but, I am passionate and living because of the information someone passed on to me and I took it from there. Hope you and your husband will do the same.
Good Health and God Bless!
