More than 50% of Saudi adults have unhealthy cholesterol levels, with dangerously low “good” cholesterol (HDL) being the most common and serious problem, according to a 2026 review in the International Journal of Endocrinology. Low HDL cholesterol is the strongest predictor of heart disease and early death in the Saudi population, yet current treatments focus mainly on lowering “bad” cholesterol instead. The combination of genetic factors, Western-style diets, and sedentary lifestyles has created an epidemic where heart disease causes 45% of all deaths in Saudi Arabia.
A new review shows that over half of Saudi adults have unhealthy cholesterol levels, making heart disease the leading cause of death in the Kingdom. According to Gram Research analysis, the problem isn’t just about one type of cholesterol—it’s about low “good” cholesterol (HDL) and high triglycerides, which are particularly dangerous. The review reveals that current treatments focus too much on lowering “bad” cholesterol while ignoring these other harmful patterns. Researchers say the combination of genetic factors, Western-style diets, and sedentary lifestyles has created a perfect storm for heart disease in Saudi Arabia, and new prevention strategies are urgently needed.
Key Statistics
A 2026 review in the International Journal of Endocrinology found that more than 50% of Saudi adults have dyslipidemia (unhealthy cholesterol levels), with cardiovascular disease accounting for 45% of all deaths in the Kingdom.
According to the 2026 review, low HDL cholesterol (good cholesterol) is the most common and important lipid abnormality in Saudi Arabia and is significantly related to both all-cause mortality and cardiovascular disease death.
The review identified that dyslipidemia prevalence exceeds 50% in Saudi adults with high rates also appearing in adolescents, indicating the cholesterol crisis begins in childhood and varies significantly by region and gender.
Research shows that the Saudi population’s unique cholesterol pattern—characterized by low HDL and high triglycerides—differs from Western populations and requires treatment strategies beyond current LDL-lowering medications.
The Quick Take
- What they studied: Why cholesterol problems are so common in Saudi Arabia and how they lead to heart disease and early death
- Who participated: This is a review article that analyzed existing research about Saudi adults and teenagers with cholesterol problems, rather than conducting a new study with participants
- Key finding: More than 50% of Saudi adults have unhealthy cholesterol levels, with low “good” cholesterol (HDL) being the most dangerous pattern and the strongest predictor of heart disease and death
- What it means for you: If you’re Saudi or live in Saudi Arabia, you have a higher-than-average chance of having unhealthy cholesterol. Getting screened early and making lifestyle changes can help prevent heart disease, though you may need new types of treatment beyond current medications
The Research Details
This is a review article, which means researchers didn’t conduct new experiments. Instead, they gathered and analyzed all the existing research about cholesterol problems in Saudi Arabia to understand the big picture. They looked at national health surveys, studied how cholesterol affects the heart, and examined what treatments are currently being used.
The researchers focused on understanding why Saudi Arabia has such high rates of cholesterol problems compared to other countries. They examined three main areas: how common the problem is, how cholesterol damages the heart, and what doctors are currently doing to treat it.
By combining information from many studies, the researchers could identify patterns and gaps in current treatment approaches that individual studies might miss.
Review articles are important because they help doctors and health officials see the whole picture instead of just one study. This particular review matters because it shows that current treatments in Saudi Arabia may not be addressing the most dangerous cholesterol problems. Understanding the specific cholesterol patterns in the Saudi population helps doctors develop better prevention and treatment strategies tailored to this population’s unique needs.
This review was published in a peer-reviewed medical journal, meaning other experts checked the work. However, as a review article rather than a new study, it summarizes existing research rather than providing brand-new data. The strength comes from analyzing multiple studies together, but the conclusions depend on the quality of those underlying studies. Readers should note this reflects research available up to the publication date and may not include the very latest findings.
What the Results Show
The review reveals that cholesterol problems are extremely common in Saudi Arabia, affecting more than half of all adults. This is significantly higher than rates in many other countries. The most dangerous pattern isn’t high “bad” cholesterol alone—it’s low “good” cholesterol (HDL) combined with high triglycerides (another type of fat in the blood).
Low HDL cholesterol emerged as the single most important cholesterol problem linked to heart disease and death in the Saudi population. This is particularly concerning because current medications focus mainly on lowering “bad” cholesterol (LDL), often ignoring the HDL problem.
The review also found that cholesterol problems start early. Teenagers in Saudi Arabia already show high rates of unhealthy cholesterol patterns, suggesting the problem begins in childhood. The rates vary significantly by region and between men and women, indicating that prevention strategies need to be customized for different groups.
The researchers identified four main causes driving this epidemic: genetic factors that make Saudis more susceptible to cholesterol problems, rapid urbanization, increasingly sedentary lifestyles, and the shift toward Western-style diets high in processed foods and unhealthy fats.
The review highlights that cardiovascular disease (heart and blood vessel disease) accounts for 45% of all deaths in Saudi Arabia—nearly half of all deaths in the country. This makes it the leading cause of death, ahead of cancer and other diseases. The economic burden is substantial, with healthcare costs rising as more people develop heart disease. The review also notes significant differences in cholesterol patterns between men and women, and between different regions of Saudi Arabia, suggesting that prevention programs need to be tailored rather than one-size-fits-all.
This review builds on decades of research showing that cholesterol is a major risk factor for heart disease worldwide. However, it highlights that Saudi Arabia’s specific cholesterol pattern—characterized by low HDL and high triglycerides—is somewhat different from patterns seen in Western countries. Previous research has focused heavily on lowering LDL cholesterol, which is important, but this review emphasizes that the Saudi population needs additional attention to raising HDL and lowering triglycerides. The findings suggest that treatment strategies developed for Western populations may not be optimal for Saudis.
As a review article, this study doesn’t provide new experimental data—it summarizes existing research. The conclusions are only as strong as the underlying studies reviewed. Some important data may be missing because not all research about Saudi cholesterol patterns has been published or is easily accessible. The review doesn’t provide specific numbers on how much each factor (diet, exercise, genetics) contributes to the problem. Additionally, the review was published in 2026, so it may not include the most recent research or newest treatment options that have emerged since then.
The Bottom Line
Strong evidence supports early screening for cholesterol problems, especially for Saudi adults and teenagers. Lifestyle changes including diet improvement and increased physical activity should be the first step for everyone. Current medications that lower LDL cholesterol are helpful but may not be enough—people with low HDL or high triglycerides may need additional or different treatments. Healthcare providers should consider genetic risk factors when deciding on treatment. New therapies targeting HDL and triglycerides are needed and should be pursued. Confidence level: High for the importance of screening and lifestyle changes; Moderate for specific medication recommendations, as new treatments are still being developed.
Everyone living in Saudi Arabia should care about this research, as the risk of cholesterol problems is very high. Adults should get their cholesterol checked regularly, and teenagers should be screened as well. People with a family history of heart disease should be especially vigilant. Healthcare providers in Saudi Arabia and other countries experiencing similar epidemiological transitions should use this information to develop better prevention programs. This research is less immediately relevant to people in countries with lower cholesterol prevalence rates, though the findings about HDL and triglycerides may apply more broadly.
Lifestyle changes like improved diet and increased exercise can improve cholesterol levels within 3-6 months. Medications typically show effects within 4-12 weeks. However, preventing heart disease is a long-term commitment—benefits accumulate over years and decades. People shouldn’t expect to feel immediate changes, as high cholesterol usually causes no symptoms. The real benefit is reducing the risk of heart attack or stroke, which may not occur for many years if prevention is successful.
Frequently Asked Questions
What is the most dangerous type of cholesterol problem in Saudi Arabia?
Low HDL cholesterol (good cholesterol) combined with high triglycerides is the most dangerous pattern in Saudi Arabia. Unlike Western countries where high LDL is the main problem, Saudis face a unique cholesterol profile that current medications don’t adequately address.
How common is high cholesterol in Saudi Arabia?
More than 50% of Saudi adults have unhealthy cholesterol levels according to national surveys. The problem is even appearing in teenagers, suggesting it starts early in life and is driven by genetic factors, Western diets, and sedentary lifestyles.
Can lifestyle changes improve cholesterol levels if I’m Saudi?
Yes, diet improvements and regular exercise can improve cholesterol within 3-6 months. However, because genetic factors play a significant role in the Saudi population, lifestyle changes alone may not be enough—many people will also need medication.
Why is heart disease so deadly in Saudi Arabia?
Heart disease causes 45% of all deaths in Saudi Arabia, making it the leading cause of death. The high prevalence of unhealthy cholesterol combined with rapid urbanization, sedentary lifestyles, and Western-style diets has created an epidemic that current treatment approaches don’t fully address.
What new treatments are being developed for Saudi cholesterol problems?
The review emphasizes that new therapies targeting HDL cholesterol and triglycerides are urgently needed, as current medications focus mainly on lowering LDL cholesterol. Researchers are calling for development of treatments specifically designed for the Saudi population’s unique cholesterol pattern.
