Heartburn, back pain and pregnancy: what to know

Pregnancy hormones can relax the valve between the stomach and food pipe, allowing acid to move upwards and cause burning behind the breastbone, sour taste, or discomfort after meals. As the uterus grows, posture, altered balance, and increased load on the lower back can contribute to aching or stiffness. These symptoms may be unrelated and happen at the same time. Back pain that is severe, one-sided, linked with fever or painful urination, or accompanied by abdominal tightening has a different level of concern and should not be explained away as ordinary pregnancy discomfort.

Eat smaller meals, remain upright after eating, and avoid lying down soon after food. Notice whether rich, spicy, or acidic meals trigger burning. For your back, change position regularly, use supportive seating, and keep everyday movements gentle. A warm—not hot—compress may relax tight muscles; protect your skin and stop if it feels uncomfortable. Before taking an antacid, pain reliever, supplement, or herbal product, check that it is suitable for pregnancy with your obstetric clinician or pharmacist. A physiotherapist can suggest pregnancy-appropriate movement if back pain limits walking, sleep, or daily tasks.

Seek urgent medical help for chest pressure, trouble breathing, fainting, vomiting blood, black stools, sudden severe back or abdominal pain, vaginal bleeding, fluid leakage, fever, weakness in a leg, or loss of bladder or bowel control. Contact your maternity team promptly if pain is worsening, comes with regular tightening, painful urination, or a severe headache or visual change. Arrange a routine review when heartburn or back pain keeps disturbing sleep or does not settle with simple measures.

Could my symptoms be reflux, a muscle problem, or something needing examination? Which medicines and doses are suitable during my pregnancy? What warning signs should send me to urgent care? Would a pregnancy physiotherapy assessment help my back?
