Frequent stomachaches affect many people, but how do you know when a stomachache is just a stomachache? Could it be something worse? It might just be heartburn, but one of the most common sources of a stomachache is an ulcer. Everyday Health reminds us to look out for these symptoms when a stomachache hits:

• Sharp, sudden or persistent pain
• Bloody, black or unusual vomiting
• Bloody, black or unusual stools.
  
• Weight loss
• Poor appetite
• Bloating
  
• Belching
• Nausea

If you have any of these symptoms, see your doctor immediately. These could be signs of an ulcer -- or something worse. Don't take your chances.
