Diabetes itself is not terrible, what is terrible is the complications! Among the common complications of diabetic eye disease, it appears with 4 major signals! 1, vision loss Diabetic patients optic nerve damage or fundus vasculopathy, so that the retinal tissue hypoxia and the formation of microangioma or retinal vein dilatation, white spots, hemorrhage, atherosclerosis, and even the occurrence of retinal detachment, resulting in vision loss. 2.Myopia A large amount of sugar and salt is excreted in the body of diabetic patients with urine, coupled with thirst and drinking, the osmotic pressure of blood decreases, and the osmotic pressure of atrial water also decreases, causing the lens to swell, become thicker and more convex, and the refractive power increases to form myopia. 3. Smaller pupils Diabetes causes damage to the vegetative nerves, which can affect the pupil’s diastolic function. The pupils of diabetic patients are smaller than those of normal people, and the use of pupil dilators during funduscopic examinations is not effective, and the ability to dilate the pupil is poorer than that of normal people. 4. Cataract Diabetic patients have elevated glucose levels in the blood and intraocular atrial fluid, and the metabolism of sugar in the eye is impaired, forming a substance called sorbitol, which accumulates in the crystal and causes swelling and clouding of the crystal fibers, resulting in cataract. The symptoms and performance of diabetic eye disease should be firmly grasped, and the early symptoms of diabetic eye disease should be treated promptly to avoid aggravation of the disease. Many fat people are not aware of the dangers of obesity, perhaps their blood sugar has exceeded the standard, but in the absence of medical examination led to no change in lifestyle. Many times, it is only discovered when the disease is out when they seek medical attention. Since the complications of diabetes can cause irreversible damage, timely treatment can only ensure that the condition is stable and does not continue to deteriorate, but cannot lead to complete recovery of the damaged organs. Therefore, regardless of whether you are young or not, if you are too obese, you should have regular medical checkups and not wait until your body becomes ill before seeking medical attention. Proactive prevention is far better than passive defense.
