The evidence landscape
The sources reviewed here do not establish a lifestyle plan that prevents miscarriage. A loss is not evidence that you caused it. WHO reports that about one in four pregnancies ends in miscarriage, and chromosome problems (changes in genetic material) are found in roughly half of tested first-trimester losses. A Cochrane review found insufficient evidence that vitamin supplements before or in early pregnancy prevent miscarriage.
Eleven pinned records: six evidence-register records, the 2014 recurrent-loss review, a Cochrane review of vitamin supplementation, NHS miscarriage guidance, ASRM guidance on recurrent pregnancy loss, and CDC folic-acid guidance. The Cochrane review directly tested vitamin supplementation, but no source here tests a complete lifestyle plan.
The sources do not tell us how much any one modifiable factor changes miscarriage risk for an individual. The vitamin review addresses supplements, not every food, habit, or medical cause.
When the answer changes
The sources do not tell us how much any one modifiable factor changes miscarriage risk for an individual. The vitamin review addresses supplements, not every food, habit, or medical cause. Smoking, alcohol, weight, age, health conditions, and pregnancy development are not interchangeable, and an association cannot show what caused a past loss. If you have had two or more miscarriages, talk with a healthcare provider about whether testing or treatment fits your situation. Support or counseling can also help with the emotional pain of loss.
