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.
Causes of Gas and Bloating. Bloating in the abdomen is commonly caused by gas in the intestines. One reason for too much gas is eating foods that create gas. Swallowing air while eating is often done unconsciously and may result in frequent belching during or after meals.
