One last thing
Hey bud, one last thing...What your father has may be GERD (gastroesophageal reflux disease). If you really want to solve your fathers problem, it is up to him to change his LIFESTYLE, lifestyle is the key. No eating within 2-3hours before bedtime, put blocks ( 4-6") under the head of the bed (front bed posts), no spicy foods, soda, acidic foods, coffee, carbonated drinks, eat smaller meals and chew thoroughly, I know this stuff sounds like kindergarten, but it's important and a lot of people overlook the simple things. I am in school for this type of thing if you know what i mean. The problem with GERD (gastroesophapeal reflux disease) is the weakness of the lower esophageal sphincter. It allows previously eaten food to regurgitate due to inflammation.. In order to try to reverse this the above mentioned aspects are crucial to your fathers health. GERD has a tendency to cause future problems such as esophageal cancer (not trying to scare you, just letting you know) due to the change in cell type/function. It becomes serious if it lasts for a long time, and it begins to cause other GI (gastrointestinal tract) problems. If you want some more specifics, pm me. I would be glad to help.
