Elderly people with diabetes rarely have the typical symptoms of diabetes: drinking more, eating more, urinating more and losing weight (commonly known as “three more and one less”). On the contrary, some non-specific symptoms are more common: 1. One or more of the non-specific symptoms such as fatigue, weakness, extreme thirst, frequent urination, excessive sweating, itchy skin, impotence, etc. should be thought of if two or more of them appear. 2. Shoulder joint pain. 10% of elderly patients may have periarthritis pain with moderate or severe joint movement restriction. It may be related to local non-enzymatic protein glycation. 3, diabetic myopathy, including asymmetric muscle weakness, pain and atrophy of the pelvic and lower abdominal muscles. It occurs mainly in older men and often resolves spontaneously within a few months. 4, psychosomatic changes, manifested as mental depression, depression, anxiety, pessimism, memory loss. 5, foot skin blisters, similar to II degree scalding blisters, often gradually disappear within 1 week. 6, renal papillary necrosis, usually occurs in elderly diabetic patients, often without the manifestation of back pain and fever. 7, diabetic neuropathic cachexia (prolonged gastroparesis, mild anorexia, severe vomiting or inability to eat, eventually leading to weight loss extreme wasting). 8, malignant otitis externa, a necrotizing infection caused by the Pseudomonas group. Cognitive ability decreases and the incidence of depression is high. Therefore, elderly people without diabetes should regularly test their blood sugar to ensure early diagnosis and prevention; elderly people with diabetes should monitor their blood sugar more regularly. Of course, there are many elderly people (and also people of other ages) who have symptoms of dry mouth and polyuria, but it may not necessarily be diabetes, and other diseases may not be detected. Often it is simply due to liver and kidney yin deficiency or yin deficiency and fire, at which point reasonable Chinese herbal regulation can come in handy.
