Blurred vision
When blood sugar levels are high, changes in fluids in the body can affect the lens, causing this part to swell and change the ability to converge light. As a result, patients may experience blurred vision, especially after waking up.
If blood sugar is not controlled for a long time, small blood vessels in the retina are at risk of damage, increasing the likelihood of eye complications such as diabetic retinitis.
Numb feet
The feeling of numbness or tingling in the feet in the morning may be related to peripheral nerve damage due to prolonged high blood sugar. This is one of the common complications in people with diabetes.
Symptoms are usually more obvious after waking up due to leg inactivity for many consecutive hours. If this condition occurs frequently and is accompanied by symptoms such as frequent urination, thirst or vision loss, patients should have a health check-up.
Skin rashes and itching
Prolonged high blood sugar can cause dehydration, making the skin dry and easily irritated. This is one of the causes of itching or the appearance of red patches on the skin.
Diabetes can also damage small blood vessels, affecting the skin's nourishment and recovery process. A high blood sugar environment also creates favorable conditions for bacteria and fungi to grow, increasing the risk of skin infections causing itching.
Excessive thirst
Severe thirst right from waking up is a fairly typical sign in people with diabetes. When blood glucose levels rise, the kidneys must work harder to filter and remove excess sugar from the body.
This process causes the body to lose a lot of fluid, thereby stimulating a constant thirst. If this condition occurs frequently along with other symptoms such as frequent urination or abnormal weight loss, patients should proactively check their blood sugar for timely diagnosis.
Dry mouth when waking up
Morning dry mouth is a fairly common condition in people with diabetes. The cause stems from high blood sugar, causing the body to excrete excess glucose through urine. This process causes the body to lose more water than usual, leading to thirst and dry mouth after a long night of sleep.
In addition, diabetes can also affect the activity of the salivary glands, reducing the amount of saliva secreted. If symptoms persist or are accompanied by feelings of fatigue, patients should be examined early to detect and control the disease effectively.
Morning nausea
High blood sugar can cause dehydration and disrupt the electrolyte balance in the body, thereby leading to nausea or discomfort in the stomach when you just wake up.
In addition, diabetes can damage the nerves that control the function of the stomach, causing the digestive process to take place slower than normal. This increases the risk of bloating, indigestion and feeling heavy in the morning.
