To determine whether you have diabetes or not, you mainly rely on symptoms and self-examination. Symptoms include symptoms of neuropathy such as numbness and abnormal sensation of the limbs, as well as symptoms of ischemia such as low skin temperature and hyperpigmentation, etc. Self-examination is done by touching the dorsal artery of the foot, and diabetic foot is likely to be present if the pulsation slows down or disappears.
The diabetic foot is a lesion of the vascular nerves in the foot below the ankle joint of diabetic patients, which leads to insufficient local blood supply, abnormal sensation, and skin ulceration. Infection symptoms can be severe enough to affect bones and muscles, leading to tissue necrosis or even amputation.
1. Symptoms: including neurological symptoms and ischemic symptoms, neurological symptoms mainly manifested as limb pain, numbness, sensory loss, no sweating on the diseased side of the limb, etc.; ischemic symptoms manifested as dryness of the skin on the side of the lesion, decrease in skin temperature, hyperpigmentation, muscle atrophy on the diseased side of the limb, and intermittent claudication can occur.
2. Self-examination: patients can judge for themselves by pressing and touching the local dorsalis pedis artery, if the artery pulsation is obvious, it means that the blood flow is normal; if the pulsation is weakened or disappeared, it means that the blood flow is abnormal, and there is a possibility of suffering from diabetic foot.
If you have the above symptoms or physical examination, you should go to the hospital in time to find out whether you have diabetic foot and further treatment under the guidance of the doctor.
