Visceral fat, the type of fat stored deep in the abdominal cavity around vital organs, is more than just a hidden layer of fat—it’s a significant health concern. Unlike subcutaneous fat, which lies just under the skin, visceral fat has far-reaching effects on various body systems. In this blog, we’ll dive into the specific health risks associated with visceral fat and the science behind its impact.

The Link Between Visceral Fat and Heart Disease
Visceral fat is a well-known risk factor for heart disease.
Excess visceral fat produces inflammatory substances, such as cytokines—proteins involved in cell signaling that can drive inflammation and damage blood vessels. These substances are produced as the body perceives excessive visceral fat as a threat, triggering an immune response and releasing pro-inflammatory signals that contribute to the development of atherosclerosis (plaque buildup in the arteries). This increases the risk of cardiovascular problems.
Studies show higher visceral fat increases heart disease risks.
The American Heart Association reports that individuals with excessive abdominal fat are at a higher risk for heart disease, even if their body mass index (BMI) is within a healthy range.
How Visceral Fat Contributes to Type 2 Diabetes
Visceral fat plays a significant role in the development of insulin resistance, a precursor to type 2 diabetes.
This type of fat releases free fatty acids into the bloodstream, which accumulate in muscles and the liver, interfering with insulin’s ability to regulate blood sugar effectively.
Additionally, visceral fat secretes inflammatory markers like cytokines and adipokines, which disrupt cellular signaling, making the body’s tissues less responsive to insulin and further impairing glucose metabolism. This then creates a cycle that exacerbates insulin resistance.
FACT: high visceral fat doubles diabetes risk, even at normal BMI.
Visceral Fat and Its Impact on Cholesterol Levels
Visceral fat plays a key role in the disruption of cholesterol metabolism by increasing low-density lipoprotein (LDL), commonly known as “bad” cholesterol, and decreasing high-density lipoprotein (HDL), or “good” cholesterol. This imbalance in cholesterol levels is a significant risk factor for cardiovascular disease.
Visceral fat releases inflammatory substances and excess fatty acids that interfere with the liver’s ability to process cholesterol properly.
Increased visceral fat also promotes the production of small, dense LDL particles, which are more likely to penetrate the walls of blood vessels and contribute to plaque buildup. As HDL levels decrease, the body’s ability to remove excess cholesterol from the bloodstream is compromised, further increasing the risk of heart disease.
The Connection Between Visceral Fat and High Blood Pressure
Visceral fat is strongly linked to hypertension (high blood pressure) through several mechanisms.
One key factor is that fat surrounding internal organs, particularly in the abdominal area, can physically compress blood vessels, leading to increased vascular resistance. This added pressure makes it more difficult for blood to flow freely, causing the heart to work harder to pump blood through the body.
Additionally, visceral fat secretes pro-inflammatory cytokines and other substances that can impair the function of blood vessels, further contributing to higher blood pressure. The accumulation of visceral fat also disrupts the balance of hormones involved in regulating blood pressure, such as aldosterone and angiotensin, which can lead to sodium retention and fluid buildup.
Over time, these combined effects can increase the risk of developing chronic hypertension and associated cardiovascular complications.
Visceral fat raises the risk for high blood pressure as much as 65% to 75% for humans according to a study published by the AHA Journal.
Increased Inflammation Caused by Visceral Fat
One of the most harmful effects of visceral fat is its ability to trigger systemic inflammation throughout the body.
Visceral fat is metabolically active and releases pro-inflammatory cytokines like interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), which contribute to chronic low-grade inflammation. These cytokines circulate through the bloodstream and can damage blood vessels, impair immune function, and disrupt normal cellular processes.
The persistent inflammation caused by visceral fat is linked to the development of various diseases, including cardiovascular disease, diabetes, and certain cancers. As the body remains in a constant state of inflammation, it becomes more vulnerable to insulin resistance, high blood pressure, and other health conditions.
Risks of Fatty Liver Disease from Visceral Fat Buildup
Non-alcoholic fatty liver disease (NAFLD) is closely linked to excess visceral fat, as the fatty tissue in the abdomen plays a key role in the condition’s development.
The free fatty acids released by visceral fat enter the bloodstream and are transported to the liver, where they accumulate. This buildup of fat in the liver triggers inflammation, which damages liver cells and impairs normal liver function.
Over time, this chronic inflammation can progress to more severe liver conditions, such as non-alcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. As visceral fat increases, so does the risk of NAFLD, highlighting the importance of managing abdominal fat to protect liver health.
How Visceral Fat Affects Hormonal Balance
Visceral fat disrupts the balance of critical hormones in the body, including insulin, cortisol, and sex hormones.
The fat cells in the abdominal area are highly active and produce the aromatase enzyme, which converts testosterone into estrogen. This conversion can lead to an imbalance in sex hormones, affecting both men and women.
In women, excess estrogen from visceral fat can contribute to hormonal disorders like polycystic ovary syndrome (PCOS), which can cause irregular periods, infertility, and other metabolic issues. In men, the conversion of testosterone to estrogen due to the aromatase enzyme can lead to lower testosterone levels, which may cause symptoms like reduced libido, erectile dysfunction, and loss of muscle mass.
Additionally, the disruption of insulin and cortisol levels due to visceral fat can contribute to insulin resistance and increased stress response, further exacerbating hormonal imbalances.
The Connection Between Visceral Fat and Certain Cancers
Emerging research has revealed a strong link between excess visceral fat and an increased risk of several types of cancer, including colorectal, breast, and pancreatic cancers.
The inflammatory environment created by visceral fat, with its release of pro-inflammatory cytokines, contributes to cellular changes that promote tumor growth. These inflammatory substances can damage DNA, create an environment conducive to cancer cell survival, and disrupt normal cell function.
A study found that individuals with high levels of visceral fat have a higher risk of developing colorectal cancer compared to those with lower levels. The chronic inflammation and hormonal imbalances associated with visceral fat further increase the likelihood of tumor development in various organs, underlining the need for fat management in cancer prevention.
Key Takeaways
Visceral fat is more than a cosmetic concern—it’s a silent threat to your health. From increasing the risk of heart disease and type 2 diabetes to contributing to inflammation, hormonal imbalances, and even cancer, the impact of visceral fat cannot be ignored.
