When the body retains excess fluid, swelling often becomes noticeable in the lower extremities due to gravity. This condition, known as edema, can develop for many reasons. Some cases are related to circulation problems that prevent blood from returning efficiently to the heart. Others may be associated with kidney conditions, liver disorders, certain medications, or hormonal changes.
Heart-related conditions can sometimes contribute to swelling because the heart becomes less effective at pumping blood throughout the body. When circulation slows, fluid may accumulate in the feet and ankles.
Kidney function also plays an important role in fluid balance. If the kidneys are unable to remove excess fluid effectively, swelling may occur in various parts of the body, including the feet.
Although swelling alone cannot diagnose a specific condition, persistent or worsening edema should not be ignored, especially if it is accompanied by shortness of breath, fatigue, chest discomfort, or rapid weight gain.
Numbness and Tingling
Occasional tingling after sitting in an awkward position is completely normal. Most people have experienced the sensation of a foot “falling asleep.”
Persistent numbness or tingling, however, may indicate a problem affecting the nerves.
Peripheral neuropathy is one possible cause. This condition occurs when nerves outside the brain and spinal cord become damaged. Individuals may experience numbness, burning sensations, reduced sensation, tingling, or weakness in the feet.
Diabetes is among the most common causes of peripheral neuropathy. Elevated blood sugar levels over time can damage nerves and reduce their ability to transmit signals properly.
Vitamin deficiencies may also contribute. Deficiencies involving vitamin B12 and certain other nutrients can affect nerve health and produce similar symptoms.
Some individuals experience numbness due to nerve compression, spinal problems, autoimmune disorders, infections, or exposure to certain medications and toxins.
When numbness becomes persistent or progressively worsens, medical evaluation can help identify the underlying cause.
Feet That Are Constantly Cold
Cold feet are not always a sign of poor health. Some people naturally have colder extremities than others, especially during colder seasons.
However, consistently cold feet may sometimes indicate circulation issues.
