If you gain several pounds over a short period, it may not be fat—it could be fluid. Rapid changes like this often happen quietly. Clothes feel tighter, rings become harder to remove and you may feel “heavier” without knowing why. Many ignore this sign completely, but it’s one of the key early clues. And now, we reach the last two signs—often the most dramatic.
2. Chest Pressure or Tightness
Not sharp pain, but pressure. A heaviness. A squeezing feeling that comes and goes. Some people mistake it for heartburn or indigestion. Others feel it when they climb stairs or even when they rest. It doesn’t always indicate heart failure, but it’s a sign worth noting. And finally, the sign that often pushes people to seek help.

1. Difficulty Lying Flat Without Feeling Breathless
If you need more pillows to sleep or feel pressure in your chest when lying down, this may be your body signaling that fluid is shifting. Many people describe relief when they sit upright. This is one of the strongest early signs, and one that should never be ignored.
