Common diseases caused by obesity

Not a pleasant subject. But some diseases are linked to obesity and caused by that. It’s a fact showed by numerous studies. It will not happen to everyone. But it’s very wise to consider the possibility and choose another path while there’s still time.

Type 2 diabetes

This means the blood sugar level is abnormal high. Too much sugar in the blood. That can be the cause of heart disease, kidney disease, stroke, amputation, and blindness.

Heritage, genes, low activity, and a poor diet are the most likely causes. Studies have shown a link between type 2 diabetes and obesity. Especially if your body weight is around the waist, it looks like obesity can make cells more resistant to insulin. So call insulin resistance.

Usually, insulin carries sugar from the blood to the cells as energy. But when insulin-resistant sugar can`t be absorbed by the cells anymore, causing a high level of sugar in the blood.

The cells producing insulin will work extra hard to keep blood sugar in balance, making them gradual to fail more and more. It’s a dangerous condition. It’s possible to have diabetes without knowing it.

It’s not as severe as Type 1 diabetes because injections of insulin aren’t needed. But it’s necessary to change to a healthy diet. With the loss of body fat, exercise, and the correct diet, it will be possible to live with this disease without medication.

High blood pressure

The heart beats to press blood through the body to provide oxygen and energy for the cells. Blood pressure measures how hard that work is.

Normal blood pressure is 120/80 mm Hg (120 over 80). Over 140 is considered too high. You will most likely not feel it. But it can cause problems like heart disease, stroke, and kidney failure. Getting your blood pressure measured by your doctor is straightforward.

It’s very much caused by obesity. Big body size will make it harder to pump the blood. Changes in lifestyle will help — loss of body weight. Healthy diet. Exercise will give a much stronger heart. But if that’s not enough medicine will be necessary.

Heart disease

The heart is our only muscle that can work nonstop 24/7 our whole life without becoming tired. To do that it has to work correctly. Heart disease describes problems affecting the heart. For example, if the heart’s own blood vessels become hard and narrow, so the heart itself doesn’t get enough blood and oxygen. It’s not hard to see that’s not a stable condition.

You can suffer from a heart attack, heart failure, sudden cardiac death, angina (chest pain) or abnormal heart rhythm (possible need for a pacemaker).

The leading cause of death in the united states is a heart attack.

Weight loss will help a lot. Just a loss of 5-10 percent of body weight will reduce the risk of heart disease. It’s hardly necessary to tell that exercise gives a stronger heart.


It happens when the flow of blood to parts of the brain stops caused by a sudden leak in a blood vessel. An overall dangerous, life-threatening condition. Brain cells can only be without oxygen up to 5 minutes before they start to die. Survive that, and the damages can be very severe and invalidating.

The most important thing to reduce the risk for a stroke is to keep the blood pressure under control, and that includes loss of weight. Obesity can increase blood pressure. The higher the pressure, the higher the risk of something is breaking.


There is a variety of different types of cancer, and it’s not always clear what causes it. There can be a mix of reasons. For example, heritage or something in our environment and everyday life. It has been studied for decades and still is. Hopefully, it will lead to new medical treatments in the future.

Cancer is the body’s own cells, starting to crow abnormal out of control. By doing so, they will increase in numbers and remove healthy body cells disturbing and shutdown normal organ functions. In the end, it will lead to death.

But thankfully, many types of cancer can be cured if discovered and treated early. Standard treatment is still operation, radiation therapy, and medication. Depending on the kinds of cancer, prognoses can be good or bad.

Gaining weight as an adult does increase the risk of cancer. It’s not clear exactly how. Fat cells may produce hormones that affect cell growth — leading to cancer. Or the same reasons that lead to overweight or obesity can cause cancer too.

The second leading cause of death in the united states is cancer.

Sleep apnea

Overweight and obesity causes sleep apnea. It’s a condition where you take breaks breathing when you’re sleeping at night. So you could be doing it right now without knowing.

It can cause daytime sleepiness, problems focusing, and even heart failures because obesity gives more fat around the neck. That makes the airway smaller and gives issues breathing. Fat around the neck and other parts of the body can also release poison substances that cause inflammation.

So of course weight loss will very much reduce the risk of sleep apnea.


It is linked to obesity too. The more bodyweight. The more pressure on the whole system. That includes joints and cartilage. Old age and genes can be the cause also. But just a weight loss of 5 percent can seriously improve your situation. It reduces stress on hips, knees, and lowers back.

Fatty liver disease

Fatty liver disease is a build-up of fat in the liver. The cause is still unknown. But it’s especially obese, middle-aged and diabetic people who are affected. But it can affect children too. It’s called a nonalcoholic disease. Because it affects people who drink very little or no alcohol in contrary to alcoholic liver disease.

It causes minimal symptoms, and there’s no known treatment. But its always recommended changing the diet and start exercising. Reduced body weight can give improved liver tests if you already have the disease. So everything counts.

Kidney disease

The kidneys clean the blood for waste products and produce urine. So it’s severe if the kidneys stop working. Because of the build-up of waste in the blood. You have to start with dialyzes treatment that goes on for the rest of your life. Either that or organ transplantation. That’s not an easy task, and it requires a possible donor.

Studies show obesity in itself can be a cause for kidney disease, and it increases the risk of high blood pressure and diabetes — known most common reasons for kidney disease.

If you are already in the early stages weight loss can slow down the disease and keep you healthy for a longer time. It helps to reduce the intake of salt. Control blood pressure and blood sugar.

All that is not meant to out shame or scare anyone. But keep in mind. The risk is there. It’s necessary to face it and react to it. But there’s hope. Just a little reduction in body weight can give a significant health improvement.
