How to recognize kidney disease in older people

Kidney disease is a serious health condition that affects millions of elderly adults around the world, yet it often goes unnoticed until it reaches advanced stages.

The kidneys, two bean-shaped organs located at the back of the abdomen, play a critical role in filtering waste from the blood, balancing body fluids, and regulating vital minerals like potassium and sodium.

As we age, kidney function naturally declines, but for some, this decline can be exacerbated by disease leading to significant health issues.

The challenge with kidney disease, particularly in older adults, is that the early symptoms can be very subtle and easily mistaken for normal signs of aging. This can delay diagnosis and treatment, leading to more severe complications over time.

Understanding and recognizing the symptoms of kidney disease can help in early detection and management, potentially slowing the progression of the disease.

One of the most common yet overlooked symptoms of kidney disease is fatigue. Older adults often experience a general feeling of tiredness and a decrease in energy levels. While this can be a typical part of aging, it’s also a sign of kidney disease.

This fatigue occurs because the kidneys are less effective at filtering toxins out of the blood, which can affect overall energy levels and muscle function.

Another subtle sign is difficulty concentrating or a general sense of confusion, which can be a result of toxins building up in the blood.

This symptom is particularly tricky because it can easily be attributed to age-related cognitive decline. However, if accompanied by other symptoms of kidney disease, it should prompt a medical evaluation.

Changes in urination are more direct symptoms and can include the urgency to urinate more often, especially at night, or the opposite—difficulties or a decrease in frequency.

Changes in the appearance of urine, such as foamy or dark urine, can also be indicators. These changes occur because the kidneys’ filtering ability is compromised, affecting urine production and the elimination of waste.

Swelling in the legs, ankles, feet, or hands can be a sign of kidney disease in elderly adults. This swelling, known as edema, occurs because the kidneys are failing to eliminate excess fluid from the body.

While swelling can be caused by a variety of health issues, when occurring alongside other kidney disease symptoms, it should not be ignored.

Poor appetite or a metallic taste in the mouth can also be associated with kidney disease. These symptoms result from the buildup of waste products in the body, which can affect taste and decrease appetite. Nausea and vomiting are possible extensions of this symptom as the condition progresses.

Another serious symptom is high blood pressure, which can both be a cause and a result of kidney disease.

High blood pressure damages the kidney’s nephrons, the tiny structures within kidneys that filter blood, and as kidney function declines, it becomes harder to control blood pressure.

Recognizing these symptoms early is crucial, especially in elderly adults. Simple blood and urine tests can help monitor kidney function.

These tests can detect the presence of protein or certain waste products in the urine, and altered levels of creatinine and urea in the blood, which are strong indicators of kidney health.

Although kidney disease is a serious and often silent threat, understanding the symptoms can lead to earlier detection and treatment, which can significantly improve quality of life in elderly individuals.

Regular check-ups and simple tests are valuable tools in combating the silent progression of kidney disease. Encouraging elderly family members to discuss changes in their body with their doctor can make a significant difference in managing and treating this challenging condition.
