Causes and top signs of kidney failure

Kidneys are two bean-shaped organs found on both sides of the body. Their primary functions include blood purification and urine production to excrete fluids from the body. However, organ failure can result in fluid buildup and causes waste buildup in the body. Kidney failure primarily affects the production of red blood cells in circulation and triggers several discomforts that should not be ignored. Here are the common causes and signs of kidney failure explained.

Primary causes of kidney failure
Kidney failure is mainly triggered due to underlying health problems, such as the following given below.

Diabetes and hypertension are the most common causes of kidney failure.
Certain autoimmune diseases can also trigger problems with organ function.
Genetic traits that trigger changes in organ function may lead to the development of chronic kidney diseases like medullary cystic kidney disease.
Regular dosages of certain prescriptions given to manage chronic illnesses can also put pressure on the organ resulting in kidney failure.
A condition called nephritis that results in the swelling of nephrons causing filtering units in the kidneys to malfunction.
Bladder problems that cause the urine to flow back into the kidneys and can result in scarring of the tissue.
Poor lifestyle choices and nutritional deficiencies can also affect the proper functioning of the organ resulting in permanent damage.

Signs of kidney failure

Fatigue
Unexplained fatigue, due to a lack of oxygenated blood in circulation, causing the brain and muscles to feel fatigued, is one of the main kidney failure signs. This symptom occurs because the kidneys are responsible for purifying blood in circulation. Also, without the kidneys, the body cannot produce a vital hormone called erythropoietin, which is necessary to produce red blood cells. As the kidneys fail to function, it causes a decrease in hormone levels and, as a result, affects oxygenated blood circulation.

Shortness of breath
Another repercussion of decreased red blood cells in circulation is shortness of breath. This happens because the cells in the body are not getting enough oxygen as a result of compromised kidney function. In addition, the lungs have excessive fluid retention when the kidneys fail to function properly. This can also result in shortness of breath as the lungs cannot store oxygen as effectively. If one experiences breathlessness despite not doing any activity that causes exertion, it could be a sign of decreasing kidney function.

Pain while urinating
Kidneys are also tasked with the important function of evacuating all fluids from the body. These organs filter out impurities from the blood and produce urine. If one is experiencing pain or difficulty while urinating, it could be a sign of early kidney failure. Retention of body fluids is another complication that affects urine output. As a result, one might also experience tightness and pressure while urinating. Changes in the color of urine are also indicative of kidney failure. Red, purple, or brown urine output is indicative of blood in the urine as the organ is unable to purify blood flowing through the vein. Also, if the urine produced is bubbly or foamy, it is a result of above-normal protein output in the urine due to deteriorated organ function.

Nausea, vomiting, and stomach pain
Kidneys help evacuate waste produced by the body by way of urination. Due to kidney failure, the waste material that collects within the body accumulates and increases the risk of uremia. This is what triggers a persistent feeling of nausea and vomiting. As the organ continues to deteriorate, it results in an excess accumulation of waste material inside the body, leading to stomach pain. Note that these symptoms and flare-ups vary from person to person depending on how severely the kidneys are affected.

Changes in taste
Persistent kidney problems trigger uremia, which also affects one’s taste perception. Patients complain of a metallic taste while eating or drinking familiar foods and beverages. This happens due to a toxic reaction that builds up as the kidneys fail to evacuate waste material from the body. Also, changes in taste will make a person lose interest in consuming foods and beverages altogether. This will also affect a person’s BMI. As unpurified blood continues to circulate in the body, it will even trigger symptoms of bad breath, all due to the toxic buildup of uremia.

Swelling
Edema is one of the common symptoms of kidney failure. It is a buildup of fluids in the body, normally at the extremities, that results in swelling of the hands, feet, or face. Kidneys purify blood and remove all waste material from the body through urine. Failing kidneys impair this function, resulting in a fluid buildup and edema. Noticeable swelling at the extremities and puffiness of the face without any prior indication of distress are all unmistakable signs of kidney failure.

Dizziness
Weakness in the body as a result of low oxygenated blood circulation is another symptom to watch out for with kidney disease. Often, the risk of anemia (low red blood cell count) is high among patients who suffer from kidney failure. Anemia is also the main trigger of fatigue and general weakness. This symptom will develop irrespective of whether a person does something to physically exert oneself or not. Dizziness is a common symptom experienced due to conditions like heart disease, diabetes, or even high blood pressure. Hence persistent weakness should be immediately checked to confirm if the underlying symptom is caused by kidney disease.

Decreased cognitive function
The brain also relies on freshly oxygenated blood for optimal function. Kidney failure triggers anemia, which, in turn, lowers the red blood cell count in circulation. When the brain is deprived of oxygen, one will have trouble with their memory, resulting in confusion and problems with concentration. Forgetting tasks or actions that are a part of daily routine are all signs of severe cognitive impairment. A blood test can confirm the RBC count and also check for elevated protein levels in the kidney that indicate organ failure. These symptoms should not be ignored and need urgent professional attention.

Important things to know about kidney problems

Important things to know about kidney problems

Kidney diseases are some of the most common and life-threatening conditions that affect patients worldwide. These diseases lead to kidney function failure over time. It can be caused by various factors, including environmental toxins, genetic predispositions, and unhealthy lifestyle choices. Kidney disease can lead to severe health complications such as acute renal failure (ARF), chronic kidney disease (CKD), or chronic renal failure (CRF). A healthy kidney is a sign of a healthy body and lifestyle. The function of the kidney The kidney is an essential organ that performs many functions in the body. It filters the blood, removes waste products and excess water from the body, and helps maintain a person’s balance of electrolytes like sodium and potassium. Kidneys help maintain their normal levels of salt concentration which is essential for the proper functioning of every cell tissue in the body because, without adequate amounts of salt, no cells can function properly. The kidney also plays a vital role in regulating blood pressure and volume by keeping them at appropriate levels through urine production. The kidneys also regulate fluid balance in your body by removing excess water from urine and adding extra water into the urine when necessary for your body tissues not to be dehydrated.  Kidney failure is when a person’s kidneys cannot function properly due to disease or injury; this condition can be fatal if left untreated.

Modifying homes for people with poor vision

Modifying homes for people with poor vision

One of the top reasons for low vision and blindness in people over 55 is macular degeneration. Macular degeneration causes loss of vision due to damage to the macula in the retina of the eye. It can be difficult for people with this condition to live in inaccessible homes. So, to ensure ease of maneuverability for people with macular degeneration or similar conditions, here are 13 tips to make a home low-vision friendly. Use clear and contrasting colors for walls The key to making a low-vision-friendly home is using light and dark colors. Dark colors can be complex for those with low vision, but if used intelligently, it can make all the difference. The answer lies in how light reflects off certain surfaces. If you have a bright yellow wall with black trim around it, then any space adjacent to it will be illuminated by daylight coming through windows above them. Contrasting shades like white or black help keep things cooler by reflecting out more heat than they receive from direct sunlight. Place essential items in your line of sight Ensure that important items, such as mobility aids, phones, and other necessities, are within your line of sight and not obscured by something else in the room.

Key things to know about macular degeneration

Key things to know about macular degeneration

Macular degeneration is an eye disorder that affects the macula, a tiny part of the retina that provides sharp central vision. The most common kind of this disease is age-related macular degeneration (AMD), which affects many people in our country over 60 years. While there is no cure for macular degeneration, several treatments and lifestyle changes help manage the symptoms and improve your vision so that it does not interfere with everyday life. What are the types of macular degeneration? There are two common types of the condition: Wet or exudative macular degeneration This is the more common type. It occurs when the tiny blood vessels in front of your retina get damaged and leak fluid into your eye, causing swelling, redness, and dampness. The condition can affect your central vision and cause blurry patches in the center. Central vision is the area you see directly in front of you. Dry or atrophic macular degeneration Also known as senile macular degeneration, this condition occurs when the retina does not receive sufficient oxygen due to damage from aging; it results in a breakdown of the central part of the retina (the photoreceptors). What causes this eye disorder? The risk factors include genetics and lifestyle ailments, such as high blood pressure, high cholesterol levels, and diabetes.

Nasal polyps – Symptoms, causes, and management

Nasal polyps can be a symptom of an underlying condition or occur independently. The visible signs and symptoms of nasal polyps include congestion, runny nose, loss of smell, and pressure or pain around your eyes and cheeks. A deviated septum may contribute to nasal polyps. However, they can also occur in people who do not have this condition, such as athletes who blow their noses frequently during exercise routines. Read on to learn more about nasal polyps. What are nasal polyps? Nasal polyps are small, soft growths that develop in the lining of the nasal passages and sinuses. They are also sometimes called nasal tumors or nasal corking. They are not cancerous, contagious, or caused by allergies. Nasal polyps may also be associated with other conditions like chronic rhinosinusitis (CRS), allergic rhinitis (AR), chronic sinusitis (CS), and asthma. Nasal polyps typically develop before the age of 40, and they do not usually cause symptoms until they grow larger or become inflamed or infected.  However, large nasal polyps can block airflow through your nose. If this happens, you may experience sinusitis, headaches, and a stuffy or runny nose. You may also experience difficulty breathing through one nostril at a time if large polyps block the other nostril completely.

Afib – Types, causes, symptoms, and management

Afib – Types, causes, symptoms, and management

Atrial fibrillation (Afib) occurs when the usually stable and regular electrical impulses in the heart’s upper chambers (atria) begin firing chaotically, causing them to quiver or twitch (fibrillate). This can cause blood accumulation and clotting in the atria. These clots can reach the lungs through the blood vessels and cause pulmonary embolism or can reach the brain, resulting in a stroke. Let’s look at the forms, signs, and causes of Afib and its treatment options: Types of atrial fibrillation Afib can be classified as one or more of these: First-diagnosed Afib: Regardless of symptoms or the number or length of episodes, this refers to individuals diagnosed for the first time with Afib. Asymptomatic Afib: This condition is also called silent Afib, given the lack of signs or symptoms. A random electrocardiogram (ECG) could reveal asymptomatic atrial fibrillation. Paroxysmal Afib: Two or more episodes of the conditions that spontaneously resolve within a week are categorized as paroxysmal Afib. Persistent Afib: This refers to two or more episodes of atrial fibrillation that last seven days or more. Long-term persistent Afib: If the condition persists for more than a year, it is referred to as long-term persistent Afib. Permanent Afib: This is a chronic condition that cannot be managed using common treatment options.
How to reduce sugar intake and manage blood sugar

How to reduce sugar intake and manage blood sugar

It is a known fact that too much sugar can be devastating for your health. When blood sugar is high, the body produces more insulin, which can lead to several health complications, including prediabetes and diabetes. So, you must cut down on sugar. Choosing healthy snacks and increasing fiber and probiotic intake can help. Moreover, regular exercise is essential. Here are a few tips to lower sugar intake and manage blood sugar levels naturally. Avoid carbohydrates A high intake of carbohydrates has a substantial impact on blood sugar levels. The body breaks down carbohydrates into sugars like glucose, which enters the blood. While the body requires glucose for energy, an excess can be harmful. As the amount of glucose increases, so does the amount of insulin produced by the body, leading to a greater risk of lifestyle disorders. Some foods with an abundance of carbs to stay away from are potato chips and donuts. Control your portion size If you are dealing with frequent blood sugar spikes, monitoring portion size can help. When you eat a large meal, blood glucose increases suddenly. To avoid this, eat smaller meals. You can opt for five to six small meals per day instead of two or three large ones.

Cancer that originates in the breast tissue is called breast cancer. It is the second most common cancer among women in the country. The condition is seen in women more than men. Fortunately, advancements in screening and breast cancer treatment have enabled dramatic improvements in survival rates over the years. The symptoms include changes in the texture and shape of the nipples, discharge from the nipples, and a lump in the breast.  Read on to learn the causes, types, and management options of breast cancer.  Causes of breast cancer Breast cancer occurs when abnormal breast cells divide and multiply more rapidly than healthy cells. These abnormal cells accumulate to form a lump or mass. Doctors have not been able to know the exact cause of breast cancer. However, multiple factors can trigger the chances of developing the disease, and they include: Family history and genetics The risk increases if you have parents or close relatives who have been diagnosed with breast cancer. Having gene mutations such as BRCA1 and BRCA2, which are passed down from parents to children, also increases the risk. Age The risk of breast cancer increases with advancing age.  Gender The risk of developing breast cancer is higher in women than in men.   Personal history of breast conditions The risk increases when an earlier biopsy has indicated atypical hyperplasia of the breast or lobular carcinoma in situ or if cancer has been detected in one breast.
