Cardiovascular diseases
Being overweight or obese significantly increases your risk of developing cardiovascular diseases. According to a study published in the New England Journal of Medicine in 2017, individuals who are overweight have a 32% higher risk of developing heart disease compared to those with a healthy weight (reference: DOI: 10.1056/NEJMoa1609797). The excess weight puts strain on your heart, leading to conditions such as heart attack, coronary artery disease, atherosclerosis, and congestive heart failure.
Type 2 diabetes
Carrying excess weight also raises the likelihood of developing type 2 diabetes. Research conducted by the World Health Organization (WHO) found that obesity is the leading risk factor for type 2 diabetes (reference: PMID: 17327603). The excess body fat interferes with your body’s ability to properly use insulin, leading to insulin resistance. This can escalate into diabetes, a serious condition that requires lifelong management.
High blood pressure
Another significant risk associated with excess weight is high blood pressure. A study published in The Lancet in 2019 showed that overweight individuals have a higher chance of developing hypertension (reference: DOI: 10.1016/S0140-6736(18)32279-7). Excess adipose tissue causes an increase in blood volume and puts additional strain on the blood vessels, resulting in elevated blood pressure levels.
Stroke
Being overweight or obese increases your risk of having a stroke. According to a study published in JAMA Neurology in 2019, obesity was associated with a higher occurrence of stroke (reference: DOI: 10.1001/jamaneurol.2019.0034). The excess weight contributes to the formation of blood clots, which can block arteries and restrict blood flow to the brain, increasing the likelihood of a stroke.
Certain cancers
Several types of cancer have been linked to being overweight or obese. Research conducted by the American Cancer Society found that overweight and obesity contribute to an increased risk of developing various cancers, including breast, colorectal, endometrial, kidney, pancreatic, and ovarian cancer (reference: DOI: 10.1002/cncr.32947). The underlying mechanisms are not fully understood, but hormonal imbalances and chronic inflammation due to excess body fat are believed to play a role.
Sleep apnea
Being overweight can lead to sleep apnea, a disorder characterized by interrupted breathing during sleep. A recent study published in the European Respiratory Journal in 2020 highlighted the strong association between obesity and sleep apnea (reference: DOI: 10.1183/13993003.01306-2020). The excess fat in the neck area can obstruct the airway, causing disruptions in breathing patterns and leading to poor sleep quality.
Osteoarthritis
Excess weight places significant strain on your joints, increasing the risk of developing osteoarthritis, a degenerative joint disease. A study published in Arthritis & Rheumatology in 2020 showed a clear association between obesity and osteoarthritis (reference: PMID: 32067216). The additional weight puts pressure on the joints, accelerating the breakdown of cartilage and leading to pain, stiffness, and reduced mobility.
Digestive disorders
Being overweight or obese can contribute to the development of digestive disorders such as gastroesophageal reflux disease (GERD) and gallbladder disease. A study published in JAMA Internal Medicine in 2016 revealed a positive correlation between excess body weight and the risk of GERD (reference: DOI: 10.1001/jamainternmed.2015.7927). The increased pressure on the stomach and the weakening of the lower esophageal sphincter can lead to acid reflux and other gastrointestinal issues. Additionally, obesity increases the risk of gallstones and subsequent gallbladder disease.

Coronary artery disease (CAD) refers to the narrowing of the coronary arteries that supply blood to the heart. Being overweight or obese is a significant risk factor for CAD. A study published in JAMA Cardiology in 2016 explored the association between obesity and CAD, concluding that obesity is a consistent and independent predictor of CAD (reference: DOI: 10.1001/jamacardio.2016.0385). The accumulation of fat in and around the blood vessels impairs blood flow to the heart, increasing the risk of developing CAD.
Atherosclerosis
Atherosclerosis is characterized by the building up of plaque inside the arteries, which can lead to restricted blood flow. Research published in the journal Circulation in 2018 demonstrated the direct relationship between excess weight and the development of atherosclerosis (reference: DOI: 10.1161/CIRCULATIONAHA.117.029583). The accumulation of cholesterol and other substances in the arterial walls can hamper blood flow, potentially resulting in cardiovascular events.
Congestive heart failure
Carrying excess weight increases the risk of developing congestive heart failure (CHF), a chronic heart condition where the heart fails to pump sufficient blood to meet the body’s needs. A study published in The American Journal of Cardiology in 2019 established obesity as a significant risk factor for CHF (reference: DOI: 10.1016/j.amjcard.2019.06.013). The strain on the heart due to obesity can contribute to structural and functional changes, impairing its ability to pump blood effectively.
Metabolic complications
Insulin resistance
Insulin resistance refers to a decreased sensitivity of the body’s cells to the hormone insulin. Obesity is closely associated with insulin resistance and its subsequent development into type 2 diabetes. A study published in the Journal of Clinical Investigation in 2017 investigated the pathophysiology of insulin resistance in obesity (reference: DOI: 10.1172/JCI92014). Excess adipose tissue releases inflammatory molecules that disrupt the normal functioning of insulin in the body, contributing to insulin resistance.
Metabolic syndrome
Metabolic syndrome is a cluster of conditions that includes high blood pressure, high blood sugar levels, excess abdominal fat, and abnormal cholesterol levels. Obesity is a key factor in the development of metabolic syndrome. Research published in The Journal of Clinical Endocrinology & Metabolism in 2015 demonstrated the strong relationship between obesity and metabolic syndrome (reference: DOI: 10.1210/jc.2015-1839). The underlying mechanisms involve hormonal imbalances and chronic inflammation associated with excess body weight.
Abnormal cholesterol levels
Being overweight or obese can lead to abnormal cholesterol levels, specifically high levels of low-density lipoprotein (LDL) cholesterol and triglycerides, while decreasing high-density lipoprotein (HDL) cholesterol levels. A study published in the American Journal of Epidemiology in 2018 investigated the relationship between obesity and abnormal cholesterol levels, highlighting the significant impact of weight on lipid profiles (reference: DOI: 10.1093/aje/kwy272). These abnormalities contribute to the development of cardiovascular diseases and other metabolic complications.
