Why is my constipation and rectal bleeding recurring?

Throwing up blood after drinking alcohol is a major indicator. There might be irritation or bleeding happening in your stomach. Putting your finger down your throat to make yourself puke will make things worse. You need to quit drinking booze right away and see a doctor. Don’t do anything else that will irritate your stomach more, and try to drink some water so you don’t get dehydrated. 

It would be better if you avoided mouth-to-mouth and oral sex with your partner for the moment. Viruses like hepatitis A are passed on from person to person through bodily fluids. The health of your liver would improve if you get rest, besides sticking to a diet of nourishing, healthy foods, and overloading on water. The body takes time to regenerate and heal. 

Your friend might be having a serious issue like internal bleeding. The bleeding from the bottom, stomach burning, and feeling sick could mean something is wrong inside her tummy. She needs urgent medical help to figure out what's happening and get the right treatment to stop the bleeding. 

The baby seems to be having some stomach problems. If there are any light-colored bumps on the skin, the water in the stool AKA diarrhea, and a long-lasting fever could indicate bacterial infection or intolerance. Through this process, the baby may feel very weak and can vomit frequently. You can take your kid to the doctor if they are experiencing so many symptoms and have them undergo check-ups and a prescribed treatment to fix them.

The signs you mentioned suggest you are experiencing gastric distress, which happens when the stomach can't process food properly. This often leads to gas buildup and causes discomfort. It's not related to a lack of vitamins. Try eating smaller portions, avoid spicy and oily foods, and chew your food slowly. Drinking a glass of warm water can also help you feel better.
