Unpacking the Connection Between Obesity and Disease

Obesity increases the risk of numerous noncommunicable diet-related diseases and decreases health-related quality of life, while simultaneously raising healthcare costs at both national and global levels.

Excess weight increases the risk of ischemic stroke and coronary heart disease significantly, as well as increasing the likelihood of osteoarthritis-like issues such as backache.

Diabetes

Obesity refers to an accumulation of fat that leads to body weight greater than what’s considered healthy for your age and gender. A person’s Body Mass Index (BMI) can provide an indicator if they are obese.

Being overweight increases your risk for diseases like diabetes, cardiovascular disease, high blood pressure and certain forms of cancer. Furthermore, obesity-related conditions like heartburn and gallstones, nonalcoholic fatty liver disease or polycystic kidney disease or even sleep apnea become more likely over time.

Your genes and environment both play a part in shaping your weight and chance of obesity-related conditions. For instance, having one obese parent increases your odds by 40 percent of becoming obese themselves; some illnesses and medications also play a part. Cushing’s syndrome or Prader-Willi syndrome increase this risk significantly while antidepressants, benzodiazepines or antiseizure drugs may lead to weight gain as well.

Binge eating and not getting enough exercise may contribute to obesity, but there may also be other contributing factors. Cultural beliefs, emotional problems and an insecure body image may lead to overeating. Your lifestyle may make it challenging to get sufficient physical activity – living in an area without safe places for walking or biking can exacerbate obesity issues further.

An overweight BMI of 25 or higher is considered overweight; an obesity BMI over 30 can be classified as obese. Being obese can lead to serious health problems, including heart disease, high blood pressure and joint pain; depression is more likely and stress management harder. Furthermore, having extra fat around can impair your immunity system as well as how well you breathe.

Studies have demonstrated that being severely obese can shave three years off your life expectancy, while moderate obesity can reduce it by 10 years. This is because excess fat boosts inflammation in your bloodstream and releases pro-inflammatory chemicals that damage cells and organs while leading to heart disease and other chronic illnesses.

Cardiovascular Disease

Cardiovascular disease (CVD), including heart attacks and stroke, is one of the leading causes of death worldwide, killing over 17 million annually. But many deaths due to CVD can be avoided through changing behaviors like quitting smoking and keeping an appropriate body weight, taking aspirin and statin medications as well as improving eating habits by decreasing fats, salt and sugar consumption. A successful CVD prevention strategy must include this element.

Obesity increases your risk for cardiovascular disease by raising your blood pressure, cholesterol and sugar levels. It may also lead to inflammation as well as conditions like gallbladder disease and fatty liver disease – all which pose risks that must be mitigated through exercise in order to ward off CVD. Additionally, being overweight reduces exercise capacity – another key element for warding off CVD.

Obese individuals are at greater risk for cardiovascular disease (CVD) than their non-obese peers, particularly if they also suffer from conditions like high blood pressure and diabetes. To reduce your CVD risk, losing weight and making healthy lifestyle changes such as eating more fruits and vegetables, cutting back on saturated fat intake, decreasing salt consumption and only drinking moderate quantities of alcohol are key steps towards prevention.

Obesity increases your risk of dying from heart attack or stroke by twofold, while shortening life span by up to 10 years, according to the Centers for Disease Control and Prevention.

Causes of CVD vary; obesity being one major contributor. Other risk factors can include family history, diet and lack of physical activity as well as having high levels of triglycerides or cholesterol as well as having genetic disorders.

An unhealthy level of body fat makes exercise harder, but cultural expectations around body size also play a factor. One study revealed that Hispanic and Black adults had lower rates of regular physical activity compared to white peers; furthermore, Hispanic and Black adults were more likely to be hospitalized for COVID-19 than their white peers.

High Blood Pressure

People with excess body fat are at an increased risk for high blood pressure, due to extra strain placed upon the heart and blood vessels to transport oxygen around the body. Over time, this strain can damage arteries, kidneys and organs such as the brain – increasing risk factors for heart disease and stroke, which are leading causes of mortality in the United States.

Obese people tend to have higher systolic and diastolic blood pressure than their slimmer peers. While the reasons may vary, one theory could be that obese individuals carry extra visceral fat in their abdomen that puts pressure on internal organs while decreasing blood flow to them.

Obese individuals often consume foods high in sodium content, leading to elevated blood pressure. This may be the result of eating more than their slimmer counterparts, and/or overeating as part of their weight management. Other contributing factors could include lifestyle factors like smoking or drinking heavily as well as genetic predisposition towards hypertension – with obesity being known to run in families.

Being obese increases your risk for other health conditions that contribute to high blood pressure, such as insulin resistance, type 2 diabetes and metabolic syndrome. An increased weight can contribute to these conditions by altering the way sugar is broken down within your body, increasing triglyceride and “bad” cholesterol levels in blood as well as contributing to inflammation within your arteries and tissues.

Fif you want to treat or prevent high blood pressure, there are many things you can do, including losing excess weight; eating a diet rich in fruits, vegetables, whole grains and low-fat dairy products; getting regular physical activity; drinking less alcohol and using less tobacco; as well as following your doctor’s advice in making lifestyle changes to lower it and reduce related diseases. Your doctor can assist in creating a diet plan tailored specifically to you, providing support as you make these necessary changes. Ultimately though, following his/her advice is the most effective way of controlling blood pressure while also reducing its associated diseases risks.

Cancer

Weight and obesity have many negative repercussions for the body, including how it processes and stores energy. Obesity increases risk for numerous health conditions like diabetes, cardiovascular disease, high blood pressure and at least 13 types of cancer.

Overweight people are defined as having a body mass index (BMI) of 25 or higher while obese people have a BMI of 30 or above. Overweight and obesity may result from eating too many high-calorie food items or insufficient physical activity; or both together. Furthermore, medical conditions like Cushing’s syndrome, polycystic ovary syndrome depression or gastrointestinal disorders could contribute to weight gain as well.

Fatty cells’ ability to store and distribute energy determines one’s risk for diseases like type 2 diabetes, heart disease, high cholesterol, sleep apnea, osteoarthritis, and some cancers. Obesity increases your chances of dysbiosis – an imbalance in the community of microbes living within your gut microbiome which has been linked with inflammation changes, altered metabolism and even genotoxicity–all which increase cancer risks.

Studies indicate that obesity increases the risk of several forms of cancer, including breast, colon and prostate cancers as well as worse survival rates in some forms of myeloma. Furthermore, excess weight from fat may increase one’s likelihood of chronic inflammatory conditions such as non-alcoholic fatty liver disease and gallstones – both conditions known to increase an individual’s chances of certain cancers.

Obesity has been linked with reduced quality of life among cancer survivors and an increased risk of secondary primary cancers, and weight gain from excess fat may exacerbate symptoms associated with cancer treatments, including lymphedema post breast cancer surgery or incontinence post prostate cancer surgery. While research shows a healthy diet and regular physical activity can help treat or prevent obesity, many adults remain obese even after making these changes; to improve outcomes healthcare professionals and communities must collaborate.
