Early pregnancy tests work by binding the hCG hormone, from either blood or urine, to an antibody and an indicator. The antibody will only bind to hCG; other hormones will not give a positive test result. The usual indicator is a pigment molecule, present in a line across a home pregnancy urine test.
Gas and bloating is a sign that food is not being digested correctly by the body. An inadequate intake of water will cause excessive stomach bloating. Water benefits the body by aiding with digestion because it supports a majority of the body's daily functions.
A Honor Society of Nursing (STTI) answered. There are some medications that can cause bloating. Bloating is an enlarged abdomen caused by excess gas. A few medications contain sugars that some people cannot completely digest, which can cause excess gas and bloating. Other medications include ingredients that stop the enzymes in your body from digesting your food. Talk to your doctor about switching medications if you are taking any that are causing bloating.
