A general practitioner has emphasised the importance of recognising subtle symptoms that are frequently ignored or mistaken for other conditions, but which could actually signal diabetes. It is estimated that six million people in the UK have diabetes, with many unaware of their condition.
Dr Saira Bano, GP, Obesity Specialist, and Co-Founder of SwiftDoctor, explained: “When most people think about diabetes, they picture the classic signs such as excessive urination or heightened thirst. However, warning signs can often be much more subtle. Many individuals live with symptoms for months or even years, dismissing them as normal effects of a busy lifestyle, ageing, or stress. This delay in seeking medical advice means the condition may progress unnoticed.”
Dr Bano has outlined several symptoms that people should watch for:

Recurrent thrush or genital infections: Repeated episodes of thrush or other fungal infections, especially when they persist despite treatment, may indicate underlying issues. High blood sugar levels can encourage yeast growth, increasing the risk of fungal infections around the genital area. If these infections frequently recur alongside symptoms like increased thirst, tiredness, or frequent urination, consulting a GP is advisable.
Blurred vision that comes and goes: Temporary changes in eyesight, such as periods of blurred vision, can be wrongly attributed to needing new glasses or eye strain. Fluctuations in blood sugar levels can alter the shape of the eye’s lens, causing vision to blur intermittently. Such changes should not be ignored, particularly when accompanied by other symptoms.
Slow-healing cuts and frequent skin infections: Minor injuries like cuts, grazes, or insect bites that take longer than expected to heal may be a sign. High blood sugar can impair circulation and immune function, delaying wound healing and increasing susceptibility to infections. It is important to discuss prolonged healing times with a healthcare professional.
Tingling, burning, or numbness in the feet: Unusual sensations such as tingling, burning, pins and needles, or numbness in the feet or hands are often dismissed as poor circulation or ageing. However, elevated blood sugar levels can damage nerves, sometimes signalling diabetes before diagnosis. Persistent symptoms should be evaluated promptly.
Dark, velvety patches of skin: Some individuals develop darker, thickened, velvety patches of skin, commonly on the back of the neck, underarms, or in skin folds such as the groin. Known as acanthosis nigricans, this condition is strongly linked to insulin resistance, which can precede type 2 diabetes. While not everyone with these skin changes will develop diabetes, they serve as an important indicator to check blood sugar levels with a healthcare provider.
Recognising these subtle signs can facilitate earlier diagnosis and management of diabetes, potentially preventing complications. Dr Bano emphasises the value of seeking medical advice if any of these symptoms are present.
