Can constipation make you feel bloated and extremely nauseous with burping? I only put two and two together, I've been constipated for a few weeks badly, and had bad stomach bloating, burping, sickness badly especially after eating for the past week. I know I'm constipated because I'm passing one or two little bits (so sorry tmi) although I am going everyday, it's also really hard. I've never felt so sick with constipation though so not sure whether this could be the culprit?
