1. Cold or Cool Feet
Cold or cool feet can be an early warning sign of peripheral artery disease (PAD), a condition where narrowed arteries reduce blood flow to the limbs. Since the feet are farthest from the heart, they are particularly vulnerable to diminished circulation, which leads to a lower temperature compared to the rest of the body.
This symptom occurs because atherosclerosis, the buildup of plaque inside arteries, restricts oxygen-rich blood from reaching the extremities. Apart from feeling cold, the skin on the feet may appear pale or bluish, indicating insufficient blood supply.
If you notice persistently cold feet, especially if accompanied by other symptoms such as leg pain or numbness, it is important to have a vascular evaluation. Diagnostic tests like an ankle-brachial index (ABI) measurement can assess blood flow and help determine the severity of arterial narrowing.
2. Swelling in Ankles or Feet
Swelling, or edema, in the ankles or feet can signal heart failure or other cardiovascular issues. When the heart’s pumping efficiency decreases, fluid can accumulate in the lower extremities due to poor circulation and increased pressure in the veins.
Unlike swelling caused by injury or prolonged standing, cardiovascular-related edema is often persistent and may worsen throughout the day. It may also be accompanied by other signs such as shortness of breath or fatigue.
In patients with diabetes, swelling can be especially concerning as it may also indicate kidney problems or infection. Evaluating swelling involves a thorough clinical exam and may require echocardiography or blood tests to assess heart function and fluid balance.
Managing fluid retention typically involves treating the underlying heart condition, lifestyle changes like reducing salt intake, and sometimes diuretic medications prescribed by a healthcare provider.
