###Human: IS it possible to have infertility problems because of miscarriage? ###Assistant: Hi. How are you doing? Miscarriage is not a usual reason for infertility, but anemia is definitely a cause. From your history I presume that the bleeding of periods is quite heavy, that could be the reason for anemia. If blood smear shows an iron deficiency anemia and you are feeling weakness with gastritis, you need to know the severity of anemia, by doing a Hb % and PCV (packed cell volume). If Hb is less than 8 g/dl, then it is better to have an iron sucrose infusion, based on the calculation. If anemia is severe, your gut wall will be edematous and iron absorption from tablets will be poor. In anemia, you will have anovulatory cycles (when you are anemic body will conserve energy and hormonal balance is lost, it will save blood by delaying periods). So, that is the reason for irregular periods, when the delay of periods occur, the inner lining of the uterus thickens and as it drops out, the pain due to dilatation of cervix will occur. Pain will be relieved as soon as the clot or the mass falls out. As long as you have anovulatory cycles, to maintain a good Hb, you will need Iron tablets, Vitamin B complex, Proteins, these three components are ingredients of hemoglobin. So to have a good fertility outcome, have anemia workup done and get it fully corrected with parenteral treatment. Kindly see if the following checklist of investigations is done:  Husband- Semen analysis at least two, done four weeks apart preferably in an infertility center (examination done by andrologist), blood sugars. Wife- Blood sugars, thyroid profile. Ultrasound scans to evaluate uterus, ovaries, and adnexa. Confirm tubal patency, most important- Tube is the connection between uterus and ovaries (the bridge where sperm meets the egg and forms a baby). This is in the size of hair follicle and cannot be seen on scans. Being such a small opening, the tube can get blocked easily. So, check with HSG (X-ray with dye), or SSG (scan with dye) or laparoscopy. If all this is done and found normal, nothing can stop a pregnancy with God's will. All the best.
