Obesity and Sexuality

• Relationship between obesity and sexuality
• Research findings

Research on the interaction between obesity and sexuality is limited, but some studies suggest that obesity can significantly impair sexual quality of life, particularly in women. Effective management of obesity using lifestyle changes, diet, drugs, behavioural therapies and, occasionally, weight loss surgery, may lead to improvements in self esteem, sexuality and quality of life.  

What is sexuality?

Sexuality refers to an individual's sexual attitudes, behaviours and practices. It is considered an integral part of our personality. The concept varies widely between individuals, and encompasses the physical (including sexual intercourse and sexual practices), the psychological and the cultural. For a long time, it has been recognised that medical conditions such as obesity can alter a peson's sexuality. This may manifest as reduced sexual desire and lack of self-esteem in sexual relationships. Although it is a sensitive and difficult topic to discuss, with a high potential for embarrassment, proper consideration of any issues you have may lead to improvements in your overall quality of life. Most doctors will be receptive and non-judgmental when discussing these issues with you during your consultation.

Overview of obesity

Obesity is broadly defined as an excess in body fat or, more specifically, as a body mass index (BMI) greater than 30. Obesity is increasing at an alarming rate in Australia, and has now reached epidemic proportions. It remains a serious health issue due to the various medical complications, including type 2 diabetes, high blood pressure, high cholesterol, bone problems and obstructive sleep apnoea. In addition, it may have a negative impact on your quality of life, physical functioning, self esteem, emotional well-being and social functioning. Considerable research has gone into obesity in recent years and efforts have been made to control this growing health problem. A variety of different treatments to combat obesity are available, including lifestyle changes, weight loss drugs, meal replacement programs and surgical procedures.

Relationship between obesity and sexuality

There has been considerable research on obesity and on sexuality as separate issues, but not that much on the relationship between the two. This may reflect general societal misconceptions that obesity and sexuality cannot coexist - that only thin people are attractive, and that there are no sexual opportunities for obese people. However, with over 50% of the Australian population classified as overweight or obese, it is clear that sexuality is, in fact, an important issue.

Obese individuals commonly experience some sexual dissatisfaction or sexual difficulties related to their weight. In males, for example, it has been proven that obesity can lower sexual satisfaction and cause erectile dysfunction. The relationship between obesity and female sexual dysfunction is less clear, though obesity may lead to reduced sexual desires in women. Obese people may experience social stigmatization, discrimination and prejudice because of their weight. Poor self-esteem and body image affect overall sexuality. Overweight people may feel like sexual misfits, unattractive and undesirable, causing them to avoid potential or actual sexual relationships. Generally, those people who consider their weight to be a real problem and who seek treatment are those who have the highest rates of sexual problems.

Obesity can also be related to sexuality in the reverse fashion. If you have had problems with your sexuality or have been the victim of sexual abuse, you may turn to binge or comfort eating to help deal with your experiences. Psychological issues may cause you to use your weight as a means of avoiding relationships or intimacy. A doctor or psychologist can help you to explore the underlying basis for your problems. 

Research findings

General results from recent studies show that:

• Obese individuals report higher incidences of sexual difficulties due to their weight (lack of sexual enjoyment, lack of sexual desire, difficulty with sexual performance, and avoidance of sexual encounters)
• A higher BMI is associated with a greater impairment in sexual quality of life
• Sexual quality of life is impaired in obese women more than in obese men, possibly because women place a greater importance on body image. Men, on the other hand, are more likely to have problems with sexual performance.
