Eating too much food causes long term negative impacts to overall health, including obesity and increased risk of obesity-related diseases such as diabetes and heart disease, according to the Mayo Clinic. Overeating also leads to weight gain and an increase in body mass index (BMI).
The Mayo Clinic describes a person having a BMI over 30% as obese. Obesity can cause serious health complications, including high cholesterol, high blood pressure, diabetes, heart attack and stroke. Obesity can also lead to an increased risk of cancer of the reproductive organs, breasts, rectum, liver and gallbladder. Excess weight commonly causes difficulty breathing and sleep apnea. According to Everyday Health, excessive weight and a BMI of 30 or more also increases the risk of rheumatoid arthritis and puts additional strain on arthritic joints.
In addition to the numerous negative health impacts, overeating and associated obesity commonly result in negative consequences to mental and emotional well-being. Excessive body fat limits mobility and cardiovascular health, making it more difficult to participate in regular physical activity. People suffering from obesity may feel socially isolated, which can lead to depression, feelings of shame and an overall diminished quality of life. Poor body image can compound feelings of shame and isolation, further perpetuating the negative impacts on mental and emotional health. Mental health may also be affected by other symptoms of obesity such as sexual health and performance problems, leading to feelings of low self worth and sexual inadequacy.
