Body mass index is a measurement that is used to dictate where a person falls on the weight scale. To calculate BMI, the weight of the individual in question is divided by the square of that same person’s height. Once this calculation is taken it can be used to determine a person’s level of body fat which helps doctors and weight loss professionals gauge a person’s chances of developing health issues that are associated with their weight.

Considering how important maintaining a healthy weight is, it is easy to see why knowing your BMI is so important. This measurement can help determine the type of diet best suited for you and whether you fall into dangerously high-risk areas.

The BMI Categories

As stated above, measuring your BMI is an important tool, especially for those who are struggling to fight overweight tendencies or obesity. Health professionals use this measurement to help you learn your target goal and determine the type of diet or weight loss plan you should attempt in hopes of reaching your target weight. Some may see this process as confusing but knowing your body mass index can put you ahead of the game when it comes to being and maintaining your body’s health. By dividing your weight by the square of your height, doctors and weight loss professionals can place you into one of four categories. Scoring 18.5 or lower often leads to the determination of a person being underweight. 18.5 to 24.9 is the score health professionals consider an ideal or healthy weight. 25 to 29.9 is categorized as being overweight and anyone scoring a 30 or higher is determined to be obese. Once a person reaches the obese category, they can also fall into levels of obesity that is also determined by their BMI. The higher your BMI is, the higher the obesity level.

The Risks of a High BMI

There are several risk factors for those individuals who have a higher than normal body mass index calculation. Here, we will discuss a few of them in hopes of showing just how important maintaining a healthy BMI is.


An elevated body mass index reading is often one of the first signs of cardiovascular issues. Overweight individuals often suffer from high blood pressure and high cholesterol. Both of these issues often require medication to keep under control and can contribute to more significant issues such as stroke and heart disease.

Respiratory issues such as difficulty breathing and, in some cases sleep apnea can also be linked to higher BMI and being overweight. Those who carry around extra pounds often find it difficult to breathe due to their size and build. When these issues also lead to sleep apnea, the inability to breathe when sleeping, it can be quite dangerous. Loss of focus and feeling tired often are both side effects of dealing with these respiratory issues.

Diabetes is one of the most common issues someone with a high body mass index may suffer from. Extra weight, especially when young, can lead to high blood sugar in the body. This illness can be medicated but can lead to highly dangerous issues later in life if not controlled.

Carrying additional weight, like individuals with a high BMI, can often lead to problems with the joints and in some cases the bones. One such issue you may find yourself suffering from is osteoarthritis. This pain often comes hand in hand with a high BMI.

For women, there are a few extra concerns when it comes to having a high BMI. Having issues when trying to get pregnant, and frequent hot flashes during menopause are issues many with weight issues suffer from. Having a high BMI and being overweight also makes a woman at higher risk for breast and endometrial cancer.

These are only a few examples of the serious implications a person can experience by having a high body mass index and being deemed overweight or obese. There are several other medical issues where overweight individuals find themselves at risk. Some of these include gallstones, colon cancer, kidney stones, and liver issues. This is why knowing your body mass index and doing all you can to keep it in the normal or healthy range is so important.

For women, miscarriage is another issue brought on by an overly low BMI. This is due to the malnutrition present in the body for those women who become pregnant while being extremely underweight. Taking the necessary vitamins and nutritional supplements needed may help reduce this risk in some women.
