5 ‘silent signs’ of high blood sugar: Doctor explains which symptoms really matter

Five subtle indicators of elevated blood sugar levels, as identified by health and wellness expert Glucosegurlrami, were highlighted recently. These include poor sleep quality, excessive thirst, increased urination, uncontrolled cravings, skin itchiness, and body aches or nerve pain. However, medical professionals stress that these symptoms are not exclusive to high blood sugar and may be associated with other health issues.

Dr. Himika Chawla, a Senior Consultant in Endocrinology and Diabetology at PSRI Hospital, provides insights into which symptoms warrant attention and when it is advisable to have blood sugar levels checked. Excessive thirst and frequent urination are among the symptoms most closely linked to high blood sugar, as elevated glucose levels can lead to increased water loss through urine.

Itchy skin can also be a sign of diabetes, often accompanied by fungal infections, although it is not specific to the condition and can stem from various causes. Sugar cravings, while frequently associated with high blood sugar on social media, are not a definitive indicator, as they can be influenced by diet, physical activity, sleep, and other health factors.

Poor sleep is another symptom not exclusive to high blood sugar, as stress, lifestyle, and medical conditions can impact sleep quality. Body aches and nerve pain are not specific to high blood sugar, but long-term elevated glucose levels can cause nerve damage and lead to symptoms such as burning, tingling, numbness, or pain, especially in the extremities.

Despite these symptoms, Chawla emphasizes that they alone cannot confirm high blood sugar levels, as a blood test is required for confirmation. Regular blood sugar testing is recommended for individuals experiencing multiple symptoms or exhibiting risk factors, even if they feel well, as diabetes or prediabetes can present with minimal or absent symptoms.

Screening may include fasting blood glucose and HbA1c tests, as determined by a healthcare provider.
