Common signs of poor eye health due to high blood sugar

High blood sugar can affect eyesight in several ways. For instance, it can damage the blood vessels in the eyes and trigger swelling in the eye tissues, which can change the shape of the lenses. Therefore, those with diabetes must take measures to manage their blood glucose levels. When high blood sugar affects the eyes, it leads to many noticeable symptoms. Here are five such signs of poor eye health due to high sugar.

Blurry vision
When blood sugar levels exceed a specific limit, the eye lenses swell. This distorts vision, and things appear blurry. As a result, one may find it challenging to perform tasks like driving and reading efficiently.

Glares
Eye lenses can become cloudy due to high sugar levels in the blood. Since these lenses are similar to those in cameras, the cloudiness makes it challenging to focus on things. As a result, a person experiences glares.

Floaters
Floaters are white or translucent spots in the field of vision. These spots are usually triggered by exposure to bright lights, such as early afternoon sunlight. For those with high blood sugar, floaters can be a persistent problem that blocks their sight. It happens due to the damage caused to the retina’s blood vessels by high glucose.

Faded colors
The retina is the most affected by high sugar. Since its function is to recognize colors, any damage can significantly impact one’s vision. When blood sugar levels exceed a specific limit, colors may appear faded or washed out.

Poor night vision
A type of photoreceptor cell in the retina called rods helps people see in low light. The damage to the blood vessels and nerves of the retina due to high blood sugar affects these cells, leading to night vision problems.

People with diabetes should look out for these signs of poor eye health due to high sugar. If someone experiences these symptoms, they should visit a healthcare provider to understand whether they are linked to raised blood glucose levels.

Eye problems associated with high blood sugar
If unmonitored, high blood glucose can lead to several eye conditions that trigger similar symptoms to those discussed above. Common examples of such disorders include:

Diabetic retinopathy
High blood sugar can damage the retina’s blood vessels, causing them to swell and leak. As a result, the blood flow may stop, leading to blurry vision.

Macular edema
The macula, the central portion of the retina, may swell because of leaky blood vessels caused by high blood sugar. This can make vision distorted or blurry.

Glaucoma
When high blood glucose damages the retina’s blood vessels, it may lead to the growth of new but abnormal blood vessels on the iris. This increases pressure on the eyes, causing neovascular glaucoma.

Cataracts
Cataracts are characterized by a cloudy buildup in the eye lenses. High blood sugar often increases the rate of cataract formation.

People with diabetes must undergo routine eye exams so that these conditions can be diagnosed as early as possible and treatment can begin to prevent further vision damage.

Allergies – Stages and prevention

The immune system of our bodies is constantly fighting against viruses and bacteria to keep us healthy. However, in certain cases, the immune system may also end up fighting some substances that are not always harmful. When this happens, you experience an allergic reaction. The allergens are the substances that cause the reactions. With a little carefulness, you can prevent the allergies effectively. The allergic development Even though an allergic reaction can vary from person to person, it generally progresses in the same five stages: Stage 1 The allergen enters your body through food, air, or touch, and contact the cells in your body. Stage 2 Your immune system creates immunoglobulin E, which is a type of antibody. Stage 3 This antibody enters your gastrointestinal tract or respiratory tract but does not do anything. Stage 4 The next time when you are exposed to the same allergen, the immunoglobulin E treats it as a harmful substance and reacts with it. Stage 5 24 hours after the reaction, the immune system cells move towards the areas that were affected to release certain chemicals to treat it. How to diagnose allergies Your allergies can be diagnosed by a doctor. Before visiting him or her, you must recognize the symptoms of an allergic reaction.

Anemia – Symptoms, types, and prevention

Anemia is a kind of medical condition in which an adequate amount of oxygen fails to reach one’s body’s tissues owing to the deficiency of red blood cells in their body.

It can have short-term or long-term effects and the disease can be mild or severe in nature. If one sees any symptoms suggesting that point toward anemia, it is essential to consult a doctor immediately. The signs vary from person to person and depend on the cause or their origin. Sometimes, the chronic disease causes anemia and the doctor ends up diagnosing the disease but the fact that one is suffering from anemia does not show up in the test. Sometimes, there are mild symptoms and then, with time the symptoms become more prominent indicating that the disease has penetrated one’s body more deeply. Some of the commonly found symptoms include breathing difficulties, fatigue, pale skin, chest pain, headache, dizziness, hands and feet turning cold, irregular heartbeat, and pain in the chest . Types of anemia Iron deficiency anemia This is the most common kind of anemia, which occurs due to iron deficiency.

Cancer – Its stages, diagnosis, and prevention

Cancer is a disease caused by the growth of malignant cells in the body. The formation of cells can happen anywhere, from the brain to the pancreas. Several cancerous cells clustered together form a tumor. The tumor then grows in size, spreading to other parts as well. Some cancers we know of are fatal, while some can be cured with the help of surgery, chemotherapy, and other such procedures. Let’s take a look at the stages, diagnosis, and prevention. Stages of cancer There are different stages of cancer that are classified to understand how far it has spread and the degree of treatment that may be required. Based on this, there are two bases for differentiation. Based on the numbered system, there are 4 stages. Stage 0 cancer In this stage, the cancer cells are restricted to the area of origin and they’ve not spread to any other part. Stage 1 cancer Here, the cancer cells spread to the nearby areas, but not to the lymph nodes or other parts of the body. Stage 2 and 3 cancer This indicates that cancer has spread to nearby areas as well as lymph nodes. Stage 4 cancer Cancer has spread to other parts of the body.
