There are signals throughout the body that blood sugar is out of control, damaging nerves, blood vessels and airways, and leading to a variety of diabetes complications. The latest article from MSN Healthy Living published the “12 Signs of Out-of-Control Diabetes” by Professor Tina St. John, a diabetes expert at the CDC! Changes in vision Blurred vision, difficulty reading, and halos when looking at lights at night can sometimes occur in people with diabetes. High blood sugar tends to cause problems such as blurred vision and dark spots or flashes of light when looking at things. In addition, it takes longer for the eyes of sugar users to adjust when going from a dark place to a brighter place. Hearing loss Many tiny blood vessels and nerves in the ear play a key role in the hearing process. High blood sugar can damage these blood vessels and nerves, making the risk of hearing loss twice as high in people with diabetes as in the general population. Bleeding gums In addition to bleeding, high blood sugar can lead to gum recession and severe periodontal disease. If left untreated for a long time, it can easily lead to tooth loss. Gingivitis can make it more difficult to control blood sugar, creating a vicious cycle. Dry mouth or ulcers High blood sugar can lead to dry mouth and make it more likely to develop oral pain, ulcers, inflammation and tooth decay. Brushing your teeth regularly and seeing your dentist every six months can help prevent diabetes-related oral disease. It is also important to stop smoking and to clean your dentures regularly. Dizziness and lightheadedness High blood sugar can easily cause a feeling of dizziness when you get up and stand up too fast, and a rapid heartbeat. These may occur suddenly or be accompanied by shortness of breath, chest tightness, slurred speech or loss of vision. The blood supply to the heart or brain may be reduced or obstructed at this time. You should seek help or call emergency services immediately and seek prompt medical attention. Tingling or numbness in the extremities Nerve damage can disrupt the nerve transmission signals between the extremities and the brain. High blood sugar can easily cause pins and needles sensation or numbness in the hands and feet, and pain in the feet when walking. Weakness of leg and foot muscles and unsteadiness in standing. Frequent pain in the hands and feet Damaged nerves can send confusing signals, making it difficult to synchronize the body’s response with external stimuli. A very gentle blanket touching the feet may produce pain, which is more pronounced at night. In addition, the person may feel extremely hot or cold in the hands and feet, or may feel like he or she is wearing gloves and socks. Leg cramps or pain Poor circulation can cause pain in the calves, thighs or hips when walking or performing other physical activities. The pain is relieved after rest. It is recommended that this symptom be told to the doctor and the necessary measures may need to be taken to protect the blood vessels. Bowel and bladder dysfunction When high blood sugar damages the bladder nerves, the patient has difficulty recognizing when it is time to urinate, leading to holding urine, which allows frequent bladder infections. Constipation and diarrhea can easily result if the intestinal nerves are continually damaged. The stomach’s ability to digest food is also greatly diminished, leading to vomiting and bloating. Abnormal sweating High blood sugar tends to cause some patients to sweat more frequently, especially at night or during meals. However, some patients do not sweat at all, and rarely sweat even on hot days. Also, check the soles of the feet. If the skin is dry, this indicates abnormal sweat gland function. Dry or itchy skin When blood sugar is too high, body fluids are relatively low, making it more likely to cause dry and itchy skin. Cracked skin tends to cause bacteria to invade the skin, resulting in slow healing of the infection. Other symptoms include dark spots, blisters, rashes, scaly flakes or hard pea-sized lumps on the skin. The skin may also appear stiff, waxy, cold or hairless in places. Difficulty in sexual life Sexual organs can also be negatively affected by nerve damage. High blood sugar can easily lead to difficulty in erection or short erection time in men, and can easily lead to vaginal dryness, difficulty in sexual arousal and difficulty in reaching orgasm in women. Therefore, it is important to check your blood sugar as well when you have sexual problems. Diabetes slowly destroys the body’s health and is not thought to be as easy to detect as other diseases. That’s why many people have the disease but don’t notice it. The incidence of type 2 diabetes is higher in obese people than in normal people, so it is important to have frequent medical checkups and observe your health.
