Causes and symptoms of atrial fibrillation

Atrial fibrillation (AFib) is a common heart rhythm disorder affecting millions worldwide. Understanding the causes and early signs of AFib is crucial for timely detection, intervention, and effective management. The subtle yet vital signs that indicate its presence can be mistaken as nothing serious or a symptom of some other health condition. By unraveling the mysteries behind AFib, it is essential to empower oneself with the knowledge that can lead to proactive heart health management and improved quality of life.

Causes of atrial fibrillation

Age
As one grows old, the risk of developing atrial fibrillation increases. The wear and tear on the heart’s electrical system over time can disrupt its normal rhythm and lead to AFib. Additionally, age-related conditions such as high blood pressure, heart disease, and underlying structural abnormalities can further predispose individuals to AFib.

High blood pressure
Hypertension, or high blood pressure, is a significant risk factor for atrial fibrillation. Persistent elevation in blood pressure can damage the heart’s electrical system and promote irregular heartbeats. Managing and controlling blood pressure through lifestyle modifications and appropriate healthcare interventions is crucial in reducing the risk of developing AFib.

Heart conditions and diseases
Various heart conditions and diseases can contribute to the development of atrial fibrillation. These include coronary artery disease, heart valve disorders, congenital heart defects, heart failure, and a history of heart surgery. Structural abnormalities or damage to the heart’s tissues can disrupt its electrical signals, leading to AFib.

Sleep apnea
Sleep apnea, a sleep disorder characterized by pauses in breathing during sleep, is strongly linked to atrial fibrillation. The intermittent lack of oxygen during apnea episodes can trigger irregular heart rhythms. Treating sleep apnea with continuous positive airway pressure (CPAP) therapy can help reduce the risk of AFib.

Chronic lung diseases
Individuals with chronic lung diseases, such as chronic obstructive pulmonary disease (COPD) or asthma, have an increased risk of developing atrial fibrillation.

All About Age-related Macular Degeneration

All About Age-related Macular Degeneration

Age-related macular degeneration (AMD) is one of the top causes of vision loss in people aged sixty and older. It is a disease that hampers your sharp, central vision. Central vision is pivotal to helping you see objects clearly and do tasks like driving and reading. AMD impairs your macula, the part of the eye that helps you see fine detail. It is not painful, but it kills the cells in the macula. It starts with blurred vision, but you gradually lose central sight. Seeing crooked lines is one of the initial AMD signs. In this guide, we will discuss everything related to AMD in detail. Types of AMD Dry People with dry AMD have drusen or yellow spots in the macula. Small drusen might not necessarily impair your vision, but as they grow in size and increase in number, they distort and dim your vision, especially as you read. Over time the condition worsens, and the light-sensitive cells in the macula get thinner and die eventually. If it is in the atrophic form, you will experience a blind spot in the center of the vision. Consequently, it worsens, and you lose central sight. Wet Blood vessels grow below the macula. These leak fluid and blood into the retina. So, when your vision is distorted, the straight lines look wavy. It might also lead to blind spots. At times, the blood vessels may bleed, leaving a scar and causing you to lose your central vision forever. Typically, people with age-related macular degeneration have dry AMD. But, sometimes, the dry form might eventually result in wet AMD. Only 1 in 10 people with macular degeneration get wet AMD. When you have macular degeneration, you must see your eye doctor frequently and closely monitor your eyesight. AMD symptoms The AMD symptoms depend on the stage.

Tips to Manage Age-related Macular Degeneration

Tips to Manage Age-related Macular Degeneration

Age-related macular degeneration (AMD) is a condition threatening one’s eyesight and general health. In AMD, the macula, the part of the eye that helps produce the most detailed and sharpest vision, starts to break down and thin, resulting in vision loss. It is one of the most prevalent causes of blindness in people aged 60 or older. Though there is no definite cure for AMD, some things can postpone its onset or lower its severity. Being aware of family history Family history and genetics are one of the leading causes of AMD. So, if you have a first-degree relative with AMD, your chances of developing it are also higher. Hence, you must be vigilant and educate yourself on the potential AMD signs, such as the inability to adapt to low light conditions, difficulty identifying faces, and straight lines looking wavy. Knowledge of these symptoms can help you reach out to an ophthalmologist and get timely treatment while AMD is still in an early stage. Getting routine comprehensive medical checkups In the early stages of AMD, you might not experience any symptoms. Hence, routine comprehensive eye exams with an ophthalmologist can help with timely diagnosis and treatment. It holds even for adults 40 or older with no risk factors or signs because this is when you may develop early AMD symptoms or experience changes in vision. After 65, consider increasing the frequency of eye examinations and get one every one to two years, even if you do not have any suggestive symptoms. Taking supplements A study found that supplementation with some micronutrients can lower AMD aggravation from the intermediate to the advanced stage by approximately 25%. In the market, one can find several vitamins sold over the counter claiming to help with AMD or eye-related diseases. If your eye doctor finds yellow spots on the retina in the eye dilation examination, they may prescribe them.
