Anyone throwing up this often needs to find out why. Ignoring this could be very dangerous. I was diagnosed many years ago with Crohn's Disease. I suffered for a long time before I couldn't take it anymore and ended up in a hospital ER. After I was admitted I was told that another 6 hours of being so dehydrated could have taken my life. There are many reasons this could be happening. You really need to find out what is going on. If your doctor is not giving it the attention it deserves, you may need a second opinion. Throwing up in itself can cause a list of problems. I wish you the best and hope you get the help you need soon.
So sorry about all your suffering.
If I were you I would look into the SCD program very seriously.
Doing an elimination diet is highly recommended, but for now you must adhere to a BRAT diet consisting of bananas, rice, applesauce, dry toast, soda crackers, because of your vomiting, until it subsides.
Staying well hydrated and replacing electrolytes and mineral is very important, however the long-term deficiencies caused by your digestive and G/I issues are very concerning.
Food sensitivities, low gastric acid, low digestive enzymes,
parasitic infections, Candida, Leaky Gut syndrome and Dysbacteriosis ( which is an imbalance where healthy intestinal flora is very low and/or dead).
In healthy individuals with normal levels of live intestinal flora, the colon is protected from inflammation, immune function is strong, B vitamins and K are produced/ processed efficiently, healthy bacteria help form moist soft stools, risk of colorectal related implications is substantially reduced.
Probiotics and probiotic foods should be considered as well, but only after your vomiting is resolved, to boost your healthy gut flora.
Please also consider to see a Holistic or Natural medicine Doctor who has experience in this area, specially if you feel you are not the proactive and take charge type of person.
Getting educated and doing a lot of research on this will help increase the chances of your improvement dramatically!
Beware of most conventional doctors, who may keep you in limbo, because of the limitations of the diagnostic and treatment protocols they use.
Let me know if you need any further details.
