<s>[INST] My friend's dad was diagnosed with stomach cancer last year and he actually had his entire stomach taken out. I read that people with no stomach should take liquid/chewable vitamins, ADEK vitamins & sublingual/injectable B12. Just wanted to make sure these are really recommended for people like him. [/INST] Hi, dearYes its recmmended. Because absorption of many vitamins take place in stomach. so if stomach is surgicaaly removed then deficiency of that vitamins may occur. so it is recommended to take vitamines supplements.Hope i answered your question. If you have any doubts then feel free to ask me. I will be happy to answer you. Thanks for using health care magic.Wish you a very good health. </s>
