It is dates on a calendar, a body that suddenly feels unfamiliar, and questions that arrive at night. When it happens again, <strong>recurrent miscarriage<\/strong> can feel like being pushed back to the starting line.<\/p> <p>A step\u2011by\u2011step medical plan can help: defining what <strong>recurrent miscarriage<\/strong> means, looking for treatable causes, reducing risks you can actually change, and preparing closer follow\u2011up for the next pregnancy.<\/p> <h2 id=\"whatdoctorsmeanbyrecurrentmiscarriage\">What doctors mean by recurrent miscarriage<\/h2> <h3 id=\"onemiscarriagevsrecurrentmiscarriage\">One miscarriage vs recurrent miscarriage<\/h3> <p>A single miscarriage is sadly common. Very often, it happens because the embryo had a <strong>chromosomal abnormality<\/strong> (a random copying error when chromosomes are shared). Most parents did nothing to cause it.<\/p> <p><strong>Recurrent miscarriage<\/strong> (also called recurrent pregnancy loss) is usually used when pregnancy loss happens more than once and the pattern justifies a structured evaluation.<\/p> <p>In many clinics across India, evaluation may start after <strong>two<\/strong> confirmed (clinical) miscarriages\u2014meaning the pregnancy was seen on ultrasound or confirmed by tissue testing. Some systems use <strong>three<\/strong> losses. Age, medical history, and the timing of losses can justify earlier testing.<\/p> <h3 id=\"earlylatemissedandbiochemicallosseswhytimingmatters\">Early, late, missed, and biochemical losses: why timing matters<\/h3> <ul> <li><strong>Early miscarriage<\/strong>: before ~12 weeks  <\/li> <li><strong>Later miscarriage<\/strong>: around 12 to 20\u201324 weeks of amenorrhoea  <\/li> <li><strong>Missed miscarriage<\/strong>: pregnancy stops developing without obvious bleeding, ultrasound detects it  <\/li> <li><strong>Biochemical pregnancy<\/strong>: positive hCG, then hCG falls before anything is visible on ultrasound  <\/li> <\/ul> <p>Very early loss often points towards embryo <strong>aneuploidy<\/strong> (an abnormal number of chromosomes). A later loss pushes doctors to think more about the uterus, cervix, placenta, and clotting\/immune conditions.<\/p> <h3 id=\"primaryandsecondaryrecurrentmiscarriage\">Primary and secondary recurrent miscarriage<\/h3> <ul> <li><strong>Primary recurrent miscarriage<\/strong>: losses without a previous live birth  <\/li> <li><strong>Secondary recurrent miscarriage<\/strong>: losses after at least one live birth  <\/li> <\/ul> <h2 id=\"howcommonrecurrentmiscarriageisandwhattheoutlookcanbe\">How common recurrent miscarriage is\u2014and what the outlook can be<\/h2> <ul> <li>Miscarriage occurs in about <strong>15\u201320%<\/strong> of recognised pregnancies.  <\/li> <li><strong>Recurrent miscarriage<\/strong> affects around <strong>1%<\/strong> of women of reproductive age.  <\/li> <\/ul> <p>Even when tests do not find one clear cause, the next pregnancy can still go well. In unexplained <strong>recurrent miscarriage<\/strong>, many studies show roughly <strong>65 out of 100<\/strong> people have a live birth in the next pregnancy.<\/p> <h3 id=\"maternalageandpaternalage\">Maternal age (and paternal age)<\/h3> <ul> <li><strong>Maternal age<\/strong> matters because embryo chromosome errors increase with age.  <\/li> <li><strong>Paternal age<\/strong> may contribute via sperm quality and <strong>sperm DNA fragmentation<\/strong>.  <\/li> <\/ul> <h2 id=\"causesofrecurrentmiscarriagethemainmedicalgroups\">Causes of recurrent miscarriage: the main medical groups<\/h2> <h3 id=\"embryochromosomalproblemsaneuploidy\">Embryo chromosomal problems (aneuploidy)<\/h3> <p>Embryo <strong>aneuploidy<\/strong> remains the most common recognised cause of miscarriage overall. In early losses, chromosomal abnormalities are often found in <strong>50\u201360%<\/strong> of cases.<\/p> <p>When possible, testing the pregnancy tissue (products of conception) using <strong>chromosomal microarray<\/strong> can clarify whether the loss was likely due to a random chromosome event.<\/p> <h3 id=\"parentalgeneticsbalancedtranslocation\">Parental genetics (balanced translocation)<\/h3> <p>In a small percentage of couples (often <strong>2\u20135%<\/strong>), one partner carries a <strong>balanced translocation<\/strong>.
