Macular degeneration – Types, causes, and remedies

Macular degeneration is a condition that affects a person’s vision and develops as people age. This progressive eye disorder involves the deterioration of the macula, which is a part of the eye’s retina. It is a leading cause of vision loss in older adults and may develop in one or both eyes. This condition is of two main types – dry and wet. Read further to learn about the disorder, its causes, and its types.

Dry macular degeneration
People are more likely to have dry macular degeneration than wet form. It is also less severe and develops when tiny yellow protein deposits under the macula. These deposits dry and thin the macula, causing gradual central vision loss while the peripheral vision remains intact. In the advanced stages, the dry form can progress to the wet form. People with dry macular degeneration need to test their eyes daily at home using an Amsler grid. One must consult a health expert immediately if any vision changes are observed.

Wet macular degeneration
In this condition, the blood vessels grow beneath the retina and macula and cause blood and fluid to leak into the retina. This build-up of fluid results in scarring, leading to permanent loss of central vision. The wet form can cause a sudden change in eyesight resulting in a severe loss of centralized vision when left untreated. People with wet macular degeneration may require repeated treatments.

Symptoms
Macular degeneration may not cause any symptoms during the early stages. However, as the condition progresses, it can cause distortion and blurry vision. It can result in difficulty reading, driving, and identifying colors. Macular degeneration occurs mainly in people aged over 50.

Blurred vision
Dark, blurry areas appear in the center of the vision, leading to increased blurriness in reading printed words.

Visual distortion
The person may experience visual distortions, such as straight lines that look wavy or crooked, and objects may appear distorted.

Need brighter light
It is one of the early symptoms of macular degeneration. Those affected may find reading hard or require brighter light when reading.

Difficulty recognizing faces
People may also have difficulty recognizing faces and facial expressions.

A dark spot in the field of vision
As the condition worsens, people may get a blind or dark spot in the middle of the visual field. This blank spot may also become larger as the disease progresses. Depending on the severity, visual loss can occur within months or years. If you are experiencing any of these symptoms, visit an eye specialist as soon as possible.

Causes
Researchers are yet to find out the exact cause of macular degeneration. However, certain factors may increase your risk of macular degeneration. For example, this eye condition is more common in people over 50. Family genes are linked to this condition. A person’s risk is higher if a close family member has this condition. The risk of macular degeneration increases in people who lead unhealthy lifestyle habits. An unhealthy BMI also increases the chance of developing macular degeneration and the risk of progressing to a more severe form. Consuming saturated fats in foods like butter, cheese, and meat increases the risk. A person is at a higher risk of developing this eye disorder if they suffer from cardiovascular disease.

Stages of Macular Degeneration
Macular degeneration occurs in three stages – early, intermediate, and late/advanced stages. Regarding early-stage macular degeneration, medium-sized deposits form in the retina causing changes in the macula, but vision is not affected. In the intermediate stage, there will be large-sized deposits with mild vision loss. The dry or wet form that causes loss of central vision is an indicator of late or advanced-stage macular degeneration. The time it takes for the condition to progress from early to late stage depends on factors like the size of the deposit.

Remedies
Though there is no cure for macular degeneration, there are a few tips to prevent the condition from worsening.

Include leafy greens in your diet
Leafy greens contain vitamins and antioxidants, including lutein and zeaxanthin, that help protect against cellular damage. To slow down the progress of macular degeneration, one should include spinach, kale, Swiss chard, and other green veggies in the daily meal plan.

Regular exercise
As it is more likely for people with high blood pressure, high cholesterol, or unhealthy body mass to develop macular degeneration, regular exercise is necessary. Maintaining a healthy body mass, blood pressure, and cholesterol level can slow the condition’s progress.

Healthy lifestyle habits
People diagnosed with macular degeneration should make changes to their lifestyle. Unhealthy lifestyle habits are bad for your overall health and your eyes. Such habits expose you to dangerous toxins that can trigger cellular damage.

Wear sunglasses and hats when outdoors
If you are diagnosed with this eye condition, protect your eyes from sun exposure when outdoors. Wear sunglasses that offer good protection from UVA and UVB rays and a rating of 99 to 100 percent. Another great way to keep sunlight out of your eyes is by wearing a wide-brimmed hat. Hats stop UV rays that may escape through the top or sides of the sunglasses from entering your eyes.

Consider nutritional supplements
Taking a combination of vitamin and mineral supplements may slow the progression of macular degeneration. According to experts, consuming the supplement with a formulation that includes vitamins C and E, lutein, zeaxanthin, zinc, and copper, will benefit. It is advised to consult a nutritional expert before opting for any supplement.

Manage other medical conditions
People who have other medical conditions, such as cardiovascular disease, should make efforts to control the conditions. Taking prescribed treatments on time and following your healthcare provider’s instructions is essential in keeping macular degeneration at bay.

Only in rare instances do people go completely blind with macular degeneration. The condition can only be slowed down with the above tips and by working closely with your ophthalmologist, but it cannot be reversed.

8 early arthritis signs one should not ignore

Living with arthritis can be a deeply uncomfortable experience. This is due to its myriad list of symptoms. Although there is no permanent cure for arthritis, healthcare professionals can work on a treatment plan for people to reduce pain and inflammation and improve their quality of life. To achieve those objectives, such professionals need to detect the earliest signs and symptoms of the condition. Here are some of the most common early arthritis signs: Morning stiffness Most people feel stiff in the morning when they wake up. This tightness is caused due to the overnight changing of lubrication in the joints and fascia. Another cause for morning stiffness is that the body’s natural Ibuprofen has not kicked in yet. However, this stiffness tends to go away when one moves and stretches out a little. Morning exercises are a great way to release this morning stiffness. In the case of arthritis, this stiffness and tightness simply do not go away. This happens because of the inherently deep nature of arthritis symptoms. Therefore, if an individual experiences stiffness for 30 to 45 minutes after waking up, it may be a sign of arthritis and should be checked by a medical professional. In fact, the stiffness does not occur only in the morning but also after one rests for a long time and then gets up from a comfortable position. This happens because the synovial fluid, a thick liquid found between one’s joints that reduces friction and joint damage, in one’s body becomes more gelatinous after a long period of inactivity. This is something that is caused by arthritis. Fatigue Arthritis has many subtypes, one of the most commonly found ones being rheumatoid arthritis, an autoimmune condition that causes widespread inflammation within the bones and joints in people. One of the common symptoms of this kind of arthritis is perpetual fatigue.

Poor blood circulation – Common signs and management tips

Blood circulation is one of the most important functions in the body, as vital organs depend on oxygen and nutrients supplied by the red blood cells to survive and function. However, certain factors like poor nutrition, underlying health issues, and unhealthy daily habits can reduce blood flow and disrupt circulation. So, here are a few common signs of poor blood circulation and useful tips for managing and overcoming the problem: Signs of poor blood circulation Visible swelling One of the first and most evident signs of poor blood circulation is swelling. Also referred to as edema, this swelling develops in the legs, feet, and ankles. Edema develops when the blood pools in one place instead of moving along the arteries and veins. Pooling causes the area to bulge. Edema is often noticeable along the extremities of the body. Due to the swelling, the skin around the affected area becomes taut and warm. Additionally, one might experience a sensation of heaviness and stiffness around the joints when affected by poor circulation. Numbness and tingling Blood circulation is a continuous process, with the heart pumping blood to reach all extremities of the body. So, any obstruction here can restrict the circulation resulting in a familiar tingling or sensation of numbness. Often, one experiences these sensations in the extremities of the hands and feet. The sensation may persist or flare up for short periods of time as the blood moves along veins and arteries. Many people compare this sensation to that of pricks caused by pins and needles. The severity of this symptom depends on how severely the circulation has been affected. Skin and hair problems The blood contains essential proteins that promote skin health and hair growth. Poor circulation deprives the skin of these essential nutrients and triggers visible changes in its color and texture.

9 common mistakes truck drivers should avoid

The freight industry is experiencing rapid growth. In today’s interconnected world, we rely heavily on trucks and trailers to transport a wide range of goods. However, driving a truck is not as simple as some may think. Whether you’re a rookie or a veteran truck driver, it’s important to exercise caution to avoid any accidents or mishaps when you are on the road. Here are 9 errors all truck drivers should avoid on the road: Crossing speed limits When transporting goods, it’s understandable to have a deadline to meet. However, unforeseen circumstances and road hazards may cause delays. It’s important to resist the urge to speed or exceed the recommended speed limit. According to truck driving laws in the country, a single axle can carry up to 20,000 lbs, while a tandem axle can carry up to 34,000 lbs. Carrying such a heavy load requires careful control, and overspeeding can lead to loss of control, risking your safety and that of others around you. It’s crucial to follow the recommended speed limit to avoid accidents that could slow you down even more. Sleep deprived riving Many truck drivers get paid by the hours they drive or the distance they cover. This can push drivers into driving for longer than recommended. According to Federal Law, truck drivers can drive up to 11 hours in a 14-hour shift, after which they must spend 10 consecutive hours away from the wheel. This leaves very little time for drivers to take care of their responsibilities and get the right amount of rest, causing them to feel drowsy behind the wheel. This may lead to: Challenged reflexes – When you’re drowsy, your reflexes slow down. This increases your response time to whatever may be happening on the road around you and increases the likelihood or severity of an accident.
