1. I am glad you are not eating at the moment any fatty foods and fizzy drinks. Your loss of apetite is from the H.Pylori, I had the same as you a very bad loss of apetite but now I am healed as I took my antibiotics course, you need to do that. Listen to me, your loss of apetite will make your body very weak and it will be hard for you to take your antibiotics, its best for you to start your antibiotics course right now before it gets to late.
When you have finished your Antibiotics course, you must do a stool sample again to see if its been clearly eliminated the h.pylori, from your stomach as it has to be a negative.
2. Than you are going to concentrate on your low stomach acid but right now you must take your Antibiotics, than we can resolve other issue.
Do 14 days quadruple therapy course for antibiotics, its effective against H.Pylori of 90%.
You are going to have 2 different antibiotics and (b i s m u t h) its like a tablet that it will protect the ulcer and it will also change your toilet poo color for while, also ask for pepto bismol its like gaviscon from your GP Doctor, you must also take PPI as like lansoprazole or omeprazole, but I would recommend you lansoprazole, you must take it twice with antibiotics. You are going to take your Antibiotics four times daily. What you have to do is take your lansoprazole or omeprazole first and wait 30mins and than take your antibiotics and than wait for in 1 hour, than eat your food. Give antibiotics for 1 hour to kill those h.pyrl and than eat your food.
Example like that as my friend listed his course as well!
9am- eat breakfast
Food you can have is white rice and fish, you can also have broccoli as vegetable because it can help kill h.pylori with antibiotics, also garlic, but have garlic as Supplements capsules, its better. Drink plenty water.
Remember Antibiotics can kill good and bad bacterias, when you have finished your course, you than must eat a lot of yogurt probiotics.
When you finished with the course, than we will move on to low stomach acid, so that you can eat normally.
