Main Symptoms of Stomach Cancer

Stomach cancer grows quietly, so early clues feel like everyday indigestion. Most people notice changes only after the tumor is large or has spread. Stomach pain is the first hint. It feels like a dull, persistent ache or burning just above the belly button and doesn’t go away with antacids. Fullness shows up early. You feel stuffed after only a few bites, or the stomach feels heavy even when you haven’t eaten. Weight loss is common. Clothes feel looser, yet you haven’t changed your diet. Nausea or vomiting may occur. Food comes back up, sometimes with blood that looks like... Learn more

Main Symptoms of Scalds

Scalds are burns caused by hot liquids or steam. They hit fast and look dramatic, but most are shallow and heal well if treated quickly. Immediate pain is the hallmark. The skin stings the moment the liquid touches it and keeps throbbing for hours. Redness appears within minutes. The area turns pink, then bright red, often with a clear line where the heat stopped. Blisters pop up quickly. Clear fluid-filled bubbles form within hours, especially on hands, face, or chest. Swelling follows. The skin puffs and feels tight, as if it’s been overfilled with air. Skin stays moist. Unlike dry... Learn more

Main Symptoms of Pediatric Burns

Burns in kids look like adult burns—only smaller, scarier, and harder to calm. Heat, chemicals, or even sparklers can damage delicate skin fast. Immediate crying is the first clue. Pain is sharp; the child pulls away and can’t be soothed right away. Skin reddens within minutes. The burn area turns pink, then bright red, often with a clear line where heat stopped. Blisters pop up quickly. Clear fluid-filled bubbles form on hands, face, or chest within hours. Swelling is dramatic. Fingers, lips, or eyelids puff and feel tight because child skin is thin and reacts fast. Color change shows depth.... Learn more

Main Symptoms of Burns

Burns injure skin and sometimes deeper tissues with heat, chemicals, or electricity. Signs range from mild redness to life-threatening wounds. Pain is immediate. The area stings or throbs; deeper burns may hurt less at first but ache later. Redness shows first. Skin turns pink within minutes, then bright red—like a bad sunburn. Blisters pop up in second-degree burns. Clear fluid-filled bubbles form within hours and can break open. Swelling follows fast. The skin puffs and feels tight, especially on fingers, eyelids, or the lips. Color changes signal depth. First-degree stays red, second-degree is blotchy red with blisters, third-degree looks white,... Learn more

Main Symptoms of Complex Congenital Heart Disease

Complex congenital heart disease means several heart structures are malformed at birth, so oxygen-rich and poor blood mix or the heart must pump against impossible odds. Symptoms start early and snowball fast. Blue color is the first clue. Lips, tongue, or fingertips look dusky or deep purple, especially during feeding or crying. Fast, labored breathing is constant. Babies breathe more quickly than normal and may grunt with each exhale. Poor weight gain follows. Infants tire at the bottle, fall asleep mid-feed, and don’t add ounces like their peers. Heart murmur is loud. A harsh, washing-machine sound is heard even without... Learn more
