When Diabetes Arrives Late — Or Has Been There for Years Undiagnosed
Type 2 diabetes becomes more common with age, and many older Nigerians are living with diabetes that was diagnosed years ago but has been managed inconsistently — or with diabetes that has simply never been diagnosed at all. In Nigerian healthcare settings, older adults are less likely than younger ones to have been offered routine blood sugar testing, less likely to have been educated about the disease, and more likely to have been managing it without regular follow-up. The consequences of this under-management accumulate over years in the form of the complications that make diabetes truly dangerous: kidney failure, blindness, nerve damage, and the foot problems that lead to amputations.
The Unique Challenges of Diabetes in Older Age
Managing diabetes in an older Nigerian adult is more complex than in younger patients for several reasons. Blood sugar that is too low (hypoglycaemia) is more dangerous in older adults than blood sugar that is mildly elevated — low blood sugar in an elderly person can cause a fall, a hip fracture, a cardiac event, or a prolonged period of confusion. The warning symptoms of hypoglycaemia — sweating, shaking, and feeling lightheaded — may be less pronounced or absent in older adults, meaning a dangerous episode can occur without obvious warning. Older adults on multiple medications face complex interactions that can destabilise blood sugar. And practical challenges — poor vision making it difficult to read medication labels, arthritis making it difficult to open medication containers, and forgetfulness in those with early cognitive decline — all compromise medication adherence.
Recognising Blood Sugar Problems in Older Adults
- High blood sugar: unusual thirst, frequent urination, blurred vision, fatigue, slow-healing wounds
- Low blood sugar (hypoglycaemia): shakiness, sweating, confusion, sudden weakness, irritability, or in severe cases — loss of consciousness
- In older adults: confusion or sudden change in behaviour may be the only sign of either high or dangerously low blood sugar
- Infected foot sores or ulcers that are not healing — this is an emergency in a diabetic person and must be seen by a doctor promptly
- Waking frequently at night to urinate — this is a common and easily missed early sign of poor blood sugar control
The Nigerian Reality of Diabetic Foot Disease
Diabetic foot complications are one of the most devastating consequences of poorly managed diabetes, and they are particularly prevalent in Nigeria where foot care is inadequate in the healthcare system, patients often do not notice injuries because of nerve damage, and the facilities to manage severe infections are limited outside major cities. Many amputations that occur in Nigerian diabetic patients could have been prevented with early intervention — identifying a wound while it is still small, cleaning and dressing it properly, and seeking medical attention before infection spreads to bone. Every Nigerian older adult with diabetes should inspect their feet every single day — looking between the toes, checking the soles, and feeling for any change in temperature or skin texture.
Practical Daily Management
- Eat three regular meals daily at consistent times — avoiding long gaps and very large single meals, both of which destabilise blood sugar
- Reduce white rice consumed in large portions, bread, sugary drinks (malt, soft drinks, sweetened tea), and fried snacks
- Increase beans, lentils, oats, vegetables, and lean protein — these raise blood sugar more slowly
- Walk for 15 to 30 minutes after your main meal if you are able
- Inspect feet daily; wash gently; dry carefully between the toes; wear clean cotton socks and properly fitting shoes
- Never walk barefoot — a diabetic person who cannot feel their feet properly will not feel a nail, stone, or wound until it becomes infected
- Keep all scheduled blood tests, eye reviews, and doctor visits — these are not optional extras
How Doc on Wheels Can Help
Blood glucose and HbA1c testing can be arranged at home through Doc on Wheels. Our doctors can review results, assess symptoms, check for signs of complications including examining the feet, and refer to specialists where needed. For older adults who find travelling to clinics difficult, or for families managing a parent or grandparent’s diabetes at home, we provide practical, accessible support.
