  3. 3.Why does garlic make me gassy?

  5. 5.Why does garlic hurt my stomach?

    Garlic can irritate the stomach and gut, especially when raw or eaten in large amounts, because of its fructans and strong sulfur compounds. People with IBS, reflux or sensitive stomachs may react more; ask a doctor if it happens often.

  7. 7.Why does garlic give me heartburn?

    Garlic, especially raw, may relax the valve between the stomach and esophagus and irritate the lining, letting acid rise and cause heartburn. If heartburn is frequent, ask a doctor.

  8. 8.Is garlic toxic to dogs?

    Yes, garlic is toxic to dogs and is considered more potent than onion. Signs can include weakness, pale gums, vomiting and dark urine, and they may appear days later, so ask a vet if your dog eats garlic.
