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! Vision loss In diabetic patients, optic nerve damage or fundus vasculopathy causes retinal tissues to lack oxygen and form microangiomas or dilated retinal veins, white spots, hemorrhages, arteriosclerosis, and even retinal detachment, resulting in vision loss. Myopia A large amount of sugar and salt is excreted in the body of diabetic patients with urine, and with thirst and excessive drinking, the osmotic pressure of blood decreases and the osmotic pressure of atrial fluid also decreases, causing the lens to swell, become thicker and more convex, and the refractive power increases to form myopia. 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 less effective and less able to dilate the pupil than normal people. Cataracts In diabetic patients, glucose levels in the blood and intraocular atrial fluid are elevated, and glucose metabolism in the eye is impaired, forming a substance called sorbitol that accumulates in the crystal, causing swelling and clouding of the crystal fibers and forming cataracts. 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 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.
