Discrimination at work is linked to high blood pressure. Icy fingers and toes: Poor circulation or Raynaud's phenomenon? Unlike fat parked on the hips and thighs, fat around the middle produces substances that can create serious health risks.

No matter what your body shape, excess fat isn't good for your health. But saddlebags and ballooning bellies are not equivalent.

When it comes to body fat, location counts, and each year brings new evidence that the fat lying deep within the abdomen is more perilous than the fat you can pinch with your fingers. If you poke your belly, the fat that feels soft is subcutaneous fat. It's found in the spaces surrounding the liver, intestines, and other organs.

It's also stored in the omentum, an apron-like flap of tissue that lies under the belly muscles and blankets the intestines. The omentum gets harder and thicker as it fills with fat.

Although visceral fat makes up only a small proportion of body fat, it's a key player in a variety of health problems. As women go through their middle years, their proportion of fat to body weight tends to increase — more than it does in men — and fat storage begins favoring the upper body over the hips and thighs.

Even if you don't actually gain weight, your waistline can grow by inches as visceral fat pushes out against the abdominal wall. Visceral fat lies in the spaces between the abdominal organs and in an apron of tissue called the omentum. Subcutaneous fat is located between the skin and the outer abdominal wall.

Body fat, or adipose tissue, was once regarded as little more than a storage depot for fat blobs waiting passively to be used for energy.

But research has shown that fat cells — particularly visceral fat cells — are biologically active. One of the most important developments [since the mids] is the realization that the fat cell is an endocrine organ, secreting hormones and other molecules that have far-reaching effects on other tissues.

Before researchers recognized that fat acts as an endocrine gland, they thought that the main risk of visceral fat was influencing the production of cholesterol by releasing free fatty acids into the bloodstream and liver.

We now know that there's far more to the story. Researchers have identified a host of chemicals that link visceral fat to a surprisingly wide variety of diseases. Subcutaneous fat produces a higher proportion of beneficial molecules, and visceral fat a higher proportion of molecules with potentially deleterious health effects.

Visceral fat makes more of the proteins called cytokines, which can trigger low-level inflammation, a risk factor for heart disease and other chronic conditions.

It also produces a precursor to angiotensin, a protein that causes blood vessels to constrict and blood pressure to rise. A tape measure is your best home option for keeping tabs on visceral fat. Measure your waistline at the level of the navel — not at the narrowest part of the torso — and always measure in the same place.

According to official guidelines, the bottom of the tape measure should be level with the top of the right hip bone, or ilium — see the illustration — at the point where the ilium intersects a line dropped vertically from the center of the armpit.

Don't suck in your gut or pull the tape tight enough to compress the area. In women, a waist circumference of 35 inches or larger is generally considered a sign of excess visceral fat, but that may not apply if your overall body size is large.

Rather than focus on a single reading or absolute cut-off, keep an eye on whether your waist is growing are your pants getting snug at the waist?

That should give you a good idea of whether you're gaining unhealthy visceral fat. Visceral fat can be measured in a variety of ways. CT scans and full-body MRIs are the most precise, but they are expensive and rarely available, so investigators often use estimates based on waist circumference or waist size in proportion to height see "Gut check".

To ensure that they're not just measuring overall obesity, researchers also check whether a person's waist circumference is higher than average for her or his body mass index BMI. Cardiovascular disease. Several studies have documented this effect. For example, a large study of European women ages 45 to 79 concluded that those with the biggest waists and those with the largest waists in relation to their hip size had more than double the risk of developing heart disease.

The risk was still nearly double even after adjustment for several other risk factors, including blood pressure, cholesterol, smoking, and BMI.

Higher visceral-fat volume also has a deleterious impact on several other heart disease risk factors. It's associated with higher blood pressure, blood sugar levels and triglyceride levels, and lower levels of HDL good cholesterol.

Taken together, these changes, known as metabolic syndrome, create a serious risk for cardiovascular disease and type 2 diabetes. Researchers at Kaiser Permanente found that people in their early 40s with the highest levels of abdominal fat, compared with those who had the least abdominal fat at that age, were nearly three times more likely to develop dementia including Alzheimer's disease by their mids to early 80s.

Dementia was not associated with increased thigh size. An easy way to determine if you may be at risk for related health problems is to measure your waist. According to the Harvard T. However, you can figure out your waist-to-hip ratio WHR at home or ask your healthcare provider to determine this measurement for you.

According to a report by the World Health Organization WHO , citing a study , a waist-to-hip ratio above. According to a study , the WHtR is particularly useful for people with type 1 diabetes.

Researchers found that having a high WHtR was one of the best indicators that a person with type 1 diabetes also has a high percentage of visceral fat. It was considered a more reliable metric than the WHR, body mass index BMI , and a body shape index ABSI. Having a larger waist circumference was also strongly associated with a high visceral fat percentage.

To calculate your WHtR at home, simply divide your waist circumference by your height. You can measure in either inches or in centimeters, as long as you measure your waist and height with the same units.

An ideal WHtR is typically no greater than. Research has found that visceral fat contributes to insulin resistance. Visceral fat can also raise blood pressure quickly. Most importantly, carrying excess visceral fat increases your risk for developing several serious and life threatening medical conditions.

These include:. When possible, exercise for at least 30 minutes every day. Make sure to include both cardio exercises and strength training.

Strength training will slowly burn more calories over time as your muscles get stronger and consume more energy. As often as possible, eliminate processed , high sugar foods from your diet and include more lean proteins , vegetables , and complex carbs , such as sweet potatoes , beans , and lentils.

Low carb diets , such as the keto diet , may also help you lose visceral fat. Discover other ways to reduce visceral fat. The stress hormone cortisol can actually increase how much visceral fat your body stores, so reducing the stress in your life will help make it easier to lose the fat.

Practice meditation , deep breathing , and other stress management tactics. Your doctor can use tests such as blood tests or an electrocardiogram ECG or EKG to check for health risks associated with high incidence of visceral fat.

They may also refer you to a nutritionist. That makes it that much more dangerous.

Age, gender, genetics, and ethnicity are broad etiological factors contributing to variation in visceral adipose tissue accumulation. Specific mechanisms responsible for proportionally increased visceral fat storage when facing positive energy balance and weight gain may involve sex hormones, local cortisol production in abdominal adipose tissues, endocannabinoids, growth hormone, and dietary fructose. Physiological characteristics of abdominal adipose tissues such as adipocyte size and number, lipolytic responsiveness, lipid storage capacity, and inflammatory cytokine production are significant correlates and even possible determinants of the increased cardiometabolic risk associated with visceral obesity. Thiazolidinediones, estrogen replacement in postmenopausal women, and testosterone replacement in androgen-deficient men have been shown to favorably modulate body fat distribution and cardiometabolic risk to various degrees.
