5. Frequent Nighttime Urination (Nocturia)
When lying down, fluid shifts and kidneys produce more urine. Needing to urinate several times at night is a commonly overlooked sign.
6. Sudden Weight Gain
A rapid gain of 2–3 pounds in a day or 5 pounds in a week can indicate fluid retention caused by heart failure.
7. Difficulty Concentrating or Confusion
Reduced blood flow to the brain can lead to memory lapses, dizziness, or difficulty focusing, especially in older adults.
8. Persistent Cough or Wheezing
Fluid in the lungs may trigger a lingering cough, sometimes producing frothy or pink-tinged mucus.
9. Swelling in the Abdomen (Ascites)
Fluid buildup in the belly causes bloating, discomfort, and sometimes loss of appetite.
10. Chest Pain or Pressure
Chest discomfort, especially if related to coronary artery disease, is a red flag. This symptom requires immediate medical attention.
11. Cold Hands and Feet
Poor circulation may cause extremities to feel cold or numb due to reduced blood flow.
12. Trouble Sleeping or Restlessness
Shortness of breath often worsens when lying flat, disrupting sleep. Many people prop themselves up with extra pillows for relief.
