Possible Causes
Generally, Bloated stomach can be related to:
- Aerophagia (Swallowing Air)
Excessive and repetitive air swallowing, resulting in burping, bloating and flatulence symptoms. It can be caused by psychological reasons, habits, or using machines that assist in breathing (CPAP machines).
- Pyloric Stenosis
Abnormal narrowing of the stomach exit. It affects babies between birth and 6 months of age and causes forceful, projectile vomiting that can lead to dehydration. Risk factors include male gender, preterm birth, and smoking during pregnancy.
- Pregnancy
Pregnancy is the term used for the period when a fetus (baby) is developing inside the mother's uterus (womb). It typically lasts about 40 weeks (just over 9 months), measured from the last menstrual period to delivery. It occurs as a result of sexual intercourse, when the egg released by the female ovary is fertilized by a sperm. Pregnancy is medically divided into three parts (trimesters). The first sign of pregnancy is typically a missed period. Morning sickness (nausea/vomiting) may accompany it.
- Benign Ovarian Tumor
- Constipation
Related Serious Diseases
Sometimes, Bloated stomach may be related to these serious diseases:
- Acute Gastric Volvulus
This medical emergency occurs when the stomach abnormally twists around itself, forming a loop. This can lead to obstruction, bleeding, and strangulation due to loss of adequate blood supply. It can happen when the structures around the stomach that help keep it in place are unusually lax or due to other structural abdominal abnormalities.
- Niemann-Pick Disease
- Intussusception
- Intestinal Malrotation
- Esophageal Varices Rupture
