1. Will Obesity Cause Infertility?
Women who are overweight or obese tend to exhibit higher levels of a hormone called leptin, which originates from fatty tissue.
This imbalance in hormones can adversely affect fertility. The amount and distribution of body fat influence the menstrual cycle via various hormonal pathways.
Higher levels of excess weight and abdominal fat increase the likelihood of encountering fertility challenges.
2. Will Obesity Affect Testosterone?
Low levels of testosterone are commonly found in obese men who do not exhibit any obvious issues with the hypothalamic-pituitary-testicular (HPT) axis.
Moderate obesity primarily reduces total testosterone levels due to decreases in sex hormone binding globulin caused by insulin resistance. In more severe cases of obesity, there is further suppression of the HPT axis, leading to decreases in free testosterone levels.
Low testosterone levels contribute to increased adiposity, creating a cycle of metabolic complications that perpetuates itself.
Obesity-related hypotestosteronemia is a functional and reversible condition, but significant weight loss is required for reversal. While testosterone therapy can result in modest reductions in fat mass, obesity alone, without symptomatic androgen deficiency, is not established as a clear indication for testosterone treatment.
3. Will Obesity Increase in the Future?
In a recent study, researchers used body mass index (BMI) as a measure to assess overweight and obesity. Consistent with the guidelines outlined by the World Health Organization (WHO), individuals with a BMI over 25 were considered overweight, while those with a BMI exceeding 30 were classified as obese.
According to the findings, it is anticipated that by 2035, approximately 51% of the world’s population, roughly equivalent to 4 billion people, will be overweight or obese. This represents a notable increase from the 38% of the population falling into this category in 2020.
Moreover, the study predicts a rise in the percentage of the global population affected by obesity from 14% in 2020 to 24% in 2035. There are also significant expectations for increased obesity rates among children and adolescents. Specifically, it is projected that between 2020 and 2035, obesity rates among boys will rise from 10% to 20%, while obesity rates among girls are expected to increase from 8% to 18% during the same period.
Within the United States, the annual increase in adult obesity is substantial at 2.1%, with the percentage of U.S. adults predicted to be affected by obesity reaching 58% by 2035. Among children, the annual increase in obesity is estimated to be 2.4%, resulting in obesity rates exceeding 40% for boys and nearly reaching 35% for girls by 2035.
4. Will Obesity Kill You?
Yes, it is true – approximately 2.8 million adults worldwide succumb to complications related to overweight or obesity annually.
In fact, being overweight or obese ranks as the fifth leading cause of death globally. The majority of these fatalities stem from complications such as diabetes, ischemic heart disease linked to excess weight, and the heightened risk of cancer associated with obesity.
5. Why Obesity Cause Hypertension?
Obesity poses a significant public health concern in contemporary society and is strongly associated with adverse cardiovascular risks. Hypertension stemming from obesity results from various interconnected mechanisms, including the inappropriate activation of the sympathetic nervous system (SNS) and renin-angiotensin-aldosterone system (RAAS), dysfunction of adipocytes, and compromised pressure natriuresis, which is further aggravated by the physical compression of the kidneys.
6. Why Obesity Cause Diabetes?
Obesity, especially when accompanied by elevated abdominal and intra-abdominal fat distribution, as well as increased levels of intrahepatic and intramuscular triglycerides, significantly heightens the risk of prediabetes and type 2 diabetes by inducing both insulin resistance and dysfunction of β-cells.
Consequently, the global rise in obesity prevalence has paralleled an increase in type 2 diabetes rates. Enhanced comprehension of the mechanisms underlying the detrimental impacts of excessive body fat on the factors implicated in the development of type 2 diabetes holds promise for the development of innovative therapeutic approaches aimed at preventing and managing this debilitating condition.
7. Why Obesity is a Problem?
Obesity negatively impacts nearly every aspect of health, leading to a shorter lifespan and increasing the risk of chronic diseases like diabetes and heart problems, while also affecting sexual function, breathing, mood, and social interactions. It’s important to note that obesity is not always a permanent state.
8. When did Obesity become a Disease?
In June 2013, the American Medical Association (AMA) House of Delegates voted to officially classify obesity as a disease warranting treatment and prevention efforts. This decision was backed by several medical societies, including the American Association of Clinical Endocrinologists, the Endocrine Society, the American College of Cardiology, the American College of Surgeons, and the American Heart Association.
The National Institutes of Health had previously recognized obesity as a disease in 1998, and the American Obesity Society followed suit in 2008. Given the AMA’s prominent position in the medical field, its declaration is anticipated to significantly influence healthcare policies, impacting insurers, industry practices, and legislative decisions.
The primary aim behind this declaration is to enhance research into the root causes of obesity, thereby facilitating the development of more effective prevention and treatment strategies, ultimately leading to better health outcomes for patients.
This shift in perspective is also expected to result in improved insurance coverage and reimbursement for healthcare providers involved in treating individuals with obesity.
Moreover, the AMA’s policy change seeks to combat the prevailing stigma associated with obesity by affirming it as a legitimate medical condition demanding attention and treatment, rather than merely a consequence of lifestyle choices.
9. How Obesity Cause Insulin Resistance?
Obesity acts as a triggering factor for diabetes by inducing insulin resistance. In individuals with obesity, adipose tissue releases higher levels of non-esterified fatty acids, glycerol, hormones, and pro-inflammatory cytokines, which can contribute to the development of insulin resistance.
Moreover, factors such as endoplasmic reticulum stress, adipose tissue hypoxia, oxidative stress, lipodystrophy, and genetic predisposition also play a role in insulin resistance.

10. How Obesity Affects Mental Health?
One study discovered that individuals with excess weight faced a 55% greater likelihood of experiencing depression throughout their lifetime compared to those without obesity.
Additional research has correlated being overweight with notable increases in major depression, bipolar disorder, and panic disorder or agoraphobia.
Numerous practical and societal factors contribute to mental health challenges for individuals living with obesity:
- Poor Body Image: Weight bias often accompanies poor body image, as individuals internalize societal stigma surrounding obesity, leading to feelings of embarrassment and dissatisfaction with their appearance.
Those grappling with excess weight may also experience anxiety over perceived judgments based on their physical appearance. - Quality of Life: Both men and women with excess weight encounter issues related to physical and occupational functioning, stemming from their size and chronic health conditions.
Inability to engage in activities they enjoy, such as attending social events or traveling, can lead to social isolation, loneliness, and increased difficulty coping with life’s challenges. Chronic pain alone has been linked to depression. - Weight Bias and Discrimination: A major obstacle for individuals dealing with weight issues is society’s negative perceptions of obesity. Weight bias includes stereotypes and attitudes that portray people with obesity as unattractive, lazy, and lacking discipline.
These biased beliefs can permeate various spheres including family dynamics, peer relationships, workplace environments, and even healthcare settings, leading to discriminatory treatment that affects self-esteem, job prospects, and the quality of healthcare received. - Physiological Factors: Obesity-related health issues can also impact mental health negatively.
Studies indicate that excess body fat and unhealthy eating habits contribute to elevated inflammatory markers, which in turn increase the risk of depression and play a role in immune system function.
