3. Fatigue and Weakness
Healthy kidneys produce a hormone called erythropoietin (EPO), which prompts the body to produce red blood cells. When kidney function declines, the production of EPO decreases, leading to anemia. Anemia can cause:
- Persistent tiredness and weakness, as your body isn’t getting enough oxygen.
- Difficulty concentrating and feeling faint, which can severely impact daily activities.
4. Shortness of Breath
Shortness of breath can occur for two reasons related to kidney dysfunction. Firstly, extra fluid in the body can build up in the lungs, making it hard to breathe. Secondly, anemia can result in less oxygen-carrying red blood cells, causing oxygen deprivation. You might experience:
- Difficulty catching your breath after minimal physical activity.
- Shortness of breath while lying down, indicating fluid buildup in the lungs.
- Chest pain or tightness, which should be evaluated immediately.
5. Skin Rashes and Itching
When kidneys fail to remove waste from the bloodstream effectively, these toxins can accumulate and cause skin issues. You might notice:
- Dry and itchy skin, which can be severe and persistent.
- Rashes that may look like small, red bumps or widespread patches.
- Darkened skin in some areas due to waste accumulation.
