One in every ten patients with type 2 diabetes in Eastern Sudan is living with a diabetic foot ulcer, a painful and potentially disabling complication that can lead to severe infections and even amputations. The finding, published in Scientific Reports, comes from the first study of its kind in the region and underscores a growing public health challenge in communities where diabetes care remains uneven and preventive services are limited. Researchers surveyed 648 adults at a tertiary hospital in Gadarif and found that 69 individuals, 10.6%, had developed foot ulcers. The study also identified two key risk factors: being male and having lived with diabetes for a longer duration. Neither age, body weight, nor lifestyle habits like smoking or alcohol use showed a significant link to ulcer development, a result that surprised some clinicians and suggests complex underlying mechanisms at play.
What Happened
A cross sectional study conducted at the diabetic center in Gadarif, Eastern Sudan, has revealed that 10.6% of patients with type 2 diabetes mellitus develop diabetic foot ulcers. The research, led by teams from the University of Khartoum and Gadarif University, involved 648 adults and is the first to quantify the burden of this complication in the region. The median age of participants was 55 years, with a median diabetes duration of seven years.
Why Public Health Officials Are Concerned
Diabetic foot ulcers are not merely painful wounds, they are a leading cause of hospital admissions, prolonged disability, and lower limb amputations in people with diabetes. In settings like Eastern Sudan, where access to specialized foot care, wound clinics, and rehabilitation services is limited, the consequences can be devastating. The study’s authors warn that without targeted interventions, the rising prevalence of diabetes in Sudan could overwhelm already strained healthcare systems and deepen health inequities.
Symptoms or Risk Factors
The study identified two significant risk factors for diabetic foot ulcers: male sex and longer duration of diabetes. Men were more than twice as likely to develop ulcers compared to women, a finding that aligns with global trends but remains poorly understood. Each additional year living with diabetes increased the risk by 8%, highlighting the cumulative damage high blood sugar inflicts on nerves and blood vessels over time.
Notably, factors like age, body mass index, smoking, and alcohol use did not show a statistically significant association with ulcer development in this population. This suggests that while lifestyle plays a role in diabetes management, the risk of foot complications may be driven more by biological and systemic factors than individual behaviors alone.
Who May Be Affected
The burden of diabetic foot ulcers falls disproportionately on individuals with long standing diabetes, particularly men. In Eastern Sudan, where diabetes awareness and regular foot screening are not yet standard practice, many patients may not recognize early warning signs, such as numbness, tingling, or minor cuts that fail to heal, until an ulcer has already formed. The study’s authors emphasize that rural and low income communities, where healthcare access is limited, are likely at even greater risk.
Prevention and Safety Guidance
Preventing diabetic foot ulcers requires a combination of patient education, regular screening, and early intervention. The study’s authors recommend several evidence based strategies:
- Annual foot examinations for all people with diabetes, including tests for nerve damage and blood flow.
- Patient education on daily foot care, proper footwear, and the importance of reporting injuries immediately.
- Community based screening programs, particularly in rural areas, to identify high risk individuals before complications arise.
- Training for primary care providers in foot assessment and ulcer prevention techniques.
- Public health campaigns to raise awareness about diabetes complications and the importance of glycemic control.
What Readers Should Know
Diabetic foot ulcers are preventable, but they require proactive management. If you or a loved one has diabetes, check your feet daily for cuts, blisters, redness, or swelling. Wear well fitted shoes and avoid walking barefoot. Schedule regular check ups with a healthcare provider, especially if you’ve had diabetes for several years or have noticed changes in sensation. Early detection and treatment can prevent ulcers from worsening and reduce the risk of serious complications, including amputation.
The study also serves as a call to action for policymakers and healthcare leaders in Sudan. Expanding access to diabetes education, foot care services, and affordable medications could significantly reduce the burden of diabetic foot ulcers and improve quality of life for thousands of patients.
Key Takeaways
- 10.6% of type 2 diabetes patients in Eastern Sudan have diabetic foot ulcers, a serious and preventable complication.
- Men and individuals with long standing diabetes are at highest risk, regardless of age or lifestyle factors.
- Prevention requires regular foot exams, patient education, and community based screening programs.
- Early detection and proper foot care can prevent ulcers from leading to infections or amputations.
Frequently Asked Questions
What is a diabetic foot ulcer?
A diabetic foot ulcer is an open sore or wound that typically develops on the bottom of the foot in people with diabetes. It occurs due to nerve damage (neuropathy) and poor blood circulation, which reduce sensation and slow healing. Without proper care, ulcers can become infected and lead to serious complications.
Why are men at higher risk for diabetic foot ulcers?
The study found that men in Eastern Sudan were more than twice as likely to develop foot ulcers compared to women. While the exact reasons are not fully understood, possible factors include differences in foot anatomy, footwear choices, healthcare seeking behaviors, and biological responses to nerve and vascular damage. More research is needed to clarify these mechanisms.
How can I prevent diabetic foot ulcers?
Prevention involves daily foot care, regular medical check ups, and maintaining good blood sugar control. Check your feet every day for cuts, blisters, or changes in color. Wear comfortable, well fitted shoes and avoid walking barefoot. Have your feet examined by a healthcare provider at least once a year, and more often if you have risk factors like long standing diabetes or previous foot problems.
What should I do if I notice a foot ulcer?
If you discover a foot ulcer, seek medical attention immediately. Do not try to treat it at home. A healthcare provider can clean the wound, assess its severity, and recommend appropriate treatment, which may include antibiotics, specialized dressings, or referral to a wound care specialist. Early intervention is critical to prevent infection and promote healing.
Are diabetic foot ulcers common in other parts of the world?
Yes, diabetic foot ulcers are a global health issue. They affect an estimated 15 to 25% of people with diabetes worldwide at some point in their lives. The risk is higher in low and middle income countries, where access to diabetes care, foot screening, and preventive services may be limited. The findings from Sudan align with broader trends but highlight the urgent need for localized prevention strategies.
