Health Risks Linked to Obesity



Obesity is a term that means you have a body mass index (BMI) of 30 or higher. It makes you more likely to have conditions including:

  •  Heart disease and stroke
  •  High blood pressure
  •  Diabetes
  • Some cancers
  •  Gallbladder disease and gallstones
  •  Osteoarthritis
  •  Gout
  •  Breathing problems, such as sleep apnea (when a person stops breathing for short episodes during sleep) and asthma

Not everyone who is obese has these problems. The risk rises if you have a family history of one of those conditions.

Also, where your weight is may matter. If it's mostly around your stomach (the "apple" shape), that may be riskier than if you have a "pear" shape, meaning that your extra weight is mostly around your hips and buttocks.

Here's a closer look at seven conditions that are linked to being obese or overweight.

1. Heart Disease and Stroke

Extra weight makes you more likely to have high blood pressure and high cholesterol. Both of those conditions make heart disease or stroke more likely.

The good news is that losing a small amount of weight can reduce your chances of developing heart disease or a stroke. Losing even more weight has been shown to lower the risk even more.

2. High Blood Pressure

High blood pressure or hypertension increases the risk of heart disease and stroke. Hypertension risk factors include obesity, drinking too much alcohol, smoking, and family history. Beta-blockers are a common treatment for hypertension.

3. Type 2 Diabetes

Most people who have type 2 diabetes are overweight or obese. You can cut your risk of developing type 2 diabetes by losing weight, eating a balanced diet, getting adequate sleep, and exercising more.

If you have type 2 diabetes, losing weight and becoming more physically active can help control your blood sugar levels. Becoming more active may also reduce your need for diabetes medication.

4. Cancer

Cancers of the colon, breast (after menopause), endometrium (the lining of the uterus), kidney, and esophagus are linked to obesity. Some studies have also reported links between obesity and cancers of the gallbladder, ovaries, and pancreas.

5. Gallbladder Disease

Gallbladder disease and gallstones are more common if you are overweight.

Ironically, weight loss itself, particularly rapid weight loss or loss of a large amount of weight, can make you more likely to get gallstones. Losing weight at a rate of about 1 pound a week is less likely to cause gallstones.

6. Osteoarthritis

Osteoarthritis is a common joint condition that most often affects the knee, hip, or back. Carrying extra pounds places extra pressure on these joints and wears away the cartilage (tissue cushioning the joints) that normally protects them.

Weight loss can ease stress on the knees, hips, and lower back and may improve the symptoms of osteoarthritis.

7. Gout

Gout is a disease that affects the joints. It happens when you have too much uric acid in your blood. The extra uric acid can form crystals that deposit in the joints.

Gout is more common in overweight people. The more you weigh, the more likely you are to get gout.

Over the short term, sudden weight changes may lead to a flare-up of gout. If you have a history of gout, check with your doctor for the best way to lose weight.

8. Sleep Apnea

Sleep apnea is a breathing condition that's linked to being overweight.

Sleep apnea can cause a person to snore heavily and to briefly stop breathing during sleep. Sleep apnea may cause daytime sleepiness and make heart disease and stroke more likely.

Weight loss often improves sleep apnea.

Today's Tips for a Healthy and Sustainable Diet

Today's Tips for a Healthy and Sustainable Diet 1. Eat More Fruits and Vegetables   Fruit and vegetables are good for our health, and most of them have a small impact on the environment. There are exceptions, as others need a lot of travel energy to keep new, so the longevity of our diets can be improved by consuming these less often.   2. Eat Locally, When in Season  If we select those that are in season where we live, locally grown foods can be a sustainable choice. Beyond their natural growing seasons, the cost of producing or storing local foods could be greater than shipping foods that are somewhere else in season.   3. Avoid Eating More than Needed, Especially Treats  By reducing excess production, consuming only what we need lowers demands on our food supply. It also helps to keep us healthy and to prevent excessive gain in weight. All useful ways to avoid unnecessary over consumption are to limit snacking on energy-dense, low-nutrient foods and...

11 Simple Health Habits Worth Adopting Into Your Life

11 Simple Health Habits Worth Adopting Into Your Life  1. Use Stairs and Furniture as Makeshift Gym Equipment Take them every chance you get if you have stairs at your home or office. However, don't stop there. Walk up and down the stairs repeatedly for a strong cardio workout. Start with a limited number of repetitions and then, as you feel stronger, increase them. 2. Drink 1 Extra Glass of Water a Day It's nothing new that drinking more water has health advantages. It helps keep your temperature normal, lubricates and cushions joints, protects your spinal cord and other sensitive tissues and gets rid of wastes through urination, sweat and bowel movements. Since 50 to 75 percent of your weight is water, it is imperative to drink some plain old H2O to keep your body working the best it can and to remain hydrated. To help your intake, you can add flavour to your water if plain water is not your favourite. 3. Replace Diet Soda with Carbonated Water The brain reacts to artificial ...
