The term abdominal girth is usually used in reference to the measurement of the circumference around the abdomen. This measurement is typically taken at the navel level to ensure that measurements over time are consistently taken in the same spot. Sometimes, however, the measurement is taken at the waist, or the narrowest point of the torso. A person's girth may change throughout his or her lifetime due to factors such as weight gain or loss, pregnancy, and certain diseases.

Many doctors and fitness professionals recommend taking measurements of abdominal girth to judge the amount of abdominal fat present. High levels of abdominal fat are linked with diabetes and heart disease. Obese individuals are more likely to have a large abdominal circumference than non-obese people, so measuring the girth of the abdomen is sometimes used as one of the methods of measuring obesity.


People on diet and exercise plans often have difficulty judging whether or not the plan is working when the total body weight, as measured on a scale, does not show a dramatic change. This may be due in part to the development of lean muscle mass, which may cause the individual to weigh more even though he or she has lost body fat. One of the ways of gauging the success of a weight loss plan is to record body measurements, including abdominal measurements, over time, and judge whether they are decreasing as the weight loss plan progresses. Sometimes, however, abdominal girth may not be the most accurate way to determine fat levels. Many women tend to store fat around the hips rather than the abdomen, and some people have thicker layers of muscle around the torso.

Many body fat percentage calculators improve accuracy by using several body measurements, including abdominal girth, to calculate how much of the individual's body is composed of fat versus lean mass. This can be a very useful way to determine the effectiveness of a diet and exercise program. Smaller measurements in relation to total body weight generally indicate a loss of body fat and a gain or maintenance of lean body mass, which is often the goal of many fat loss programs.

There are reasons other than fat gain or loss that a person's abdominal measurements may change. The circumference of a pregnant woman's abdomen will increase with development of the fetus. An increase in abdominal girth may also be an indicator of liver or intestinal problems. It is also one method of measuring gas and bloating in people who have abdominal discomfort.

When I start an exercise program and put on some muscle, I get frustrated when I step on the scale, because muscle weighs more than fat. I feel like I have been doing all this hard work and not losing any weight.

I usually feel better when I take a tape measure and start measuring the inches I have lost instead of the pounds. Measuring around my abdominal girth is one way I can tell if I am actually losing inches.

When I track my abdominal girth measurement, I usually start at my navel and go around from there. Sometimes I have gone up higher around my waist, but seem to have more consistent results when I go down a little bit lower.

@bagley-- Yes, I know what you mean. I have forgotten what it is like to have what some would consider a normal abdominal girth. In addition to my pregnancies, I have had some intestinal problems and have had stomach distention from bloating.

The size of my abdominal girth fluctuates more from this condition than from gaining or losing weight. I like to wear clothes that have some breathing room so I am not miserable with wearing something that fits too tight around my abdomen.

With each one of my pregnancies I have taken girth measurements. It was interesting to see the differences between pregnancies. With my first one, I had the smallest girth change as compared to the other two. It seems like once you have had a baby, your abdominal girth is never quite the same again -- at least that's the way it was for me.

When I gain weight, the first place it tends to go is to my abdomen. I have lost and gained weight many times from different diet plans I have followed. Some people call this yo-yo dieting as your weight constantly goes up and down.

I know this isn't really good for your body, but have had a hard time keeping the weight off once I lose it. It is frustrating after I have worked hard to lose pounds and then see my increasing abdominal girth again. I don't even have to measure it to know it is getting bigger. The number on the scale and how tight my clothes feel are the only things I need to know to start losing some weight again.
