Is an Underweight BMI Unhealthy?

While everyone knows that women with an overweight BMI are at risk from serious health problems, many women don’t believe that an underweight BMI carries nearly the same risks. After all, you can’t be too rich or too thin, right?  Most women’s fashion models are very slender, many to the point that they have a BMI in the underweight range. These ladies are held up as the standard of beauty, so it seems as if extreme thinness is the standard to which many women aspire. However, an underweight BMI in a woman can be just as dangerous as an overweight BMI if she doesn’t get adequate nutrition.

Many women who are considered underweight eat very little, so they are likely to be missing some of the vital nutrients that most people get from food. For example, if a woman doesn’t eat enough fruit or vegetables, she runs the risk of a vitamin C deficiency. Likewise, a woman who doesn’t eat meat can fall short of zinc, iron, B vitamins, or magnesium.

In addition, underweight women can place stress on their bodies just like overweight women. Every woman needs a certain amount of body fat to protect her vital organs. Besides this internal fat, other fat under the skin makes up a woman’s curves – breasts are mostly fat, and shapely hips and butts are the result of strategically placed fat filling out the figure. Women with too little body fat can suffer from anemia, persistent coldness, and menstrual problems. Also, women with a low BMI are often lacking in muscle mass, which is an important part of being able to participate in daily activities. Muscle tone also keeps women looking healthy and young.

So if you want to be sure to avoid the dangers that come from being underweight, use a BMI calculator like the one at to check your BMI and take appropriate action.

Health Risks of an Overweight BMI in Women

While it is easy for ladies to calculate their BMI using one of the many online BMI calculators for women available, it is harder to know how to use the information gained. If a woman’s BMI is greater than 25, she is considered overweight. Even worse, a BMI of 30 or more means she is obese. Here are some of the possible health risks of having an overweight BMI.

Overweight BMI Health Risks

  • Heart disease
  • Stroke
  • Cancer
  • Diabetes
  • Hypertension
  • High blood pressure
  • Sleep apnea (a condition that causes a woman to stop breathing while she’s asleep, several times per hour)
  • Liver disease
  • Infertility or other gynecological problems

Many of these health problems are related.  For example, while women with a normal range BMI can suffer from sleep apnea, obese women are at a higher risk of it.  This is because excess fat on the neck can put pressure on the windpipe, causing it to temporarily close.  And sleep apnea also increases the risk of health issues like heart attack, high blood pressure, and diabetes.  In addition, a poor quality of sleep is known to be a factor in obesity, so sleep apnea and obesity can form a vicious cycle in an untreated woman.

To help avoid these problems, it is easy for every woman to know her BMI by visiting a site like  Calculate your BMI today, and take steps to lower it if you are in the risky overweight or obese ranges.

What is BMI for Women?

The importance of BMI

You have probably heard of BMI for women, since it is everywhere on the news these days.  Dr. Oz has talked about the importance of women knowing their BMI many times on his show.  BMI is short for Body Mass Index.  Body Mass Index is a single number that makes it easy for a woman to know whether her weight is right for her height.

How to use BMI (for women)

If a woman’s BMI is too low (below 18.5) she is considered underweight.  While some would say you can never be too rich or too thin, an underweight BMI indicates that a woman may not have a healthy amount of muscle and may in fact be too skinny.  If her BMI is between 18.5 and 25, she is in the normal weight range.  This means that while a lady may not be happy with every aspect of her body shape, her mass is within the bounds considered healthy by the medical community.  When an adult female’s BMI is above 25, she is classified as overweight.  This usually means that she has too much body fat and would be healthier if she loses enough fat to get down into the normal BMI range.  However, some women can be healthy at a high BMI if they are very muscular, since muscle is more dense than fat.  Unless her BMI is over 30, which means she is obese, a woman in the overweight range does not have to worry too much about losing weight.

Those are the main ranges of BMI for women.  The underweight and obese classes are sometimes split up more finely into “severe” and “moderate” subclasses, depending on just how underweight or obese a woman is.  But you can use these BMI classes for women to determine whether you are at a healthy weight and take action to correct any weight problems you may have.
