In the field of obstetrics, lochia is the vaginal discharge after giving birth, containing blood, mucus, and uterine tissue.{{cite book |last1=Murkoff |first1=Heidi |authorlink1=Heidi Murkoff |last2=Eisenberg |first2=Arlene |last3=Hathaway |first3=Sandee |date=2002 |title=What To Expect When You're Expecting |edition=3rd |publisher=Workman |location=New York |isbn=0-7611-2132-3 |page=[https://archive.org/details/whattoexpectwhe000murk/page/383 383] |quote=This discharge of leftover blood, muscus, and tissue from your uterus, known as lochia, is normally as heavy as (and sometimes even heavier than) a menstrual period for the first three to ten postpartum days. |url-access=registration |url=https://archive.org/details/whattoexpectwhe000murk }} Lochia discharge typically continues for four to eight weeks after childbirth,{{cite journal |last1=Oppenheimer |first1=LW |last2=Sherriff |first2=EA |last3=Goodman |first3=JD |last4=Shah |first4=D |last5=James |first5=CE |date=July 1986 |title=The duration of lochia |journal=Br J Obstet Gynaecol |pmid=3755355 |volume=93 |issue=7 |pages=754–757 |doi=10.1111/j.1471-0528.1986.tb08063.x |s2cid=221487083 }} a time known as the postpartum period or puerperium. A 2016 review ties this "lochial period" to worldwide customs of postpartum confinement, a time for the new mother and baby to bond.Sharma S, van Teijlingen E, Hundley V, Angell C, Simkhada P.

Lochia is sterile for the first two days, but not so by the third or fourth day, as the uterus begins to be colonized by vaginal commensals such as non-hemolytic streptococci and E. coli.{{cite book |last=Hanretty |first=Kevin P. |others=Illustrated by Ian Ramsden and Robin Callander |date=2009 |title=Obstetrics Illustrated |edition=7th |publisher=Churchill-Livingston |isbn=978-0-7020-3066-6 |page=337 |url=http://www.us.elsevierhealth.com/ob-gyn/obstetrics-illustrated-paperback/9780702030666/ |accessdate=13 November 2013}} The Cleveland Clinic recommends that pads be used instead of tampons to absorb the fluid as materials should not be inserted in the vagina soon after childbirth.{{cite web |title=Pregnancy: Physical Changes After Delivery |url=https://my.clevelandclinic.org/health/articles/9682-pregnancy-physical-changes-after-delivery |website=Cleveland Clinic |access-date=16 August 2024}}
Stages
- Lochia rubra (or cruenta) is the first discharge, composed of blood, shreds of fetal membranes, decidua, vernix caseosa, lanugo and membranes. It is red in color because of the large amount of blood it contains. It lasts 1 to 4 days after birth, before easing to light "spotting".{{cite web |title=Postpartum Bleeding: What To Expect and How To Manage It |website=Yoppie.com |url=https://yoppie.com/blogs/fem-life/postpartum-bleeding-lochia}}{{unreliable source|date=August 2024}}
- Lochia serosa is the term for lochia that has thinned and turned brownish or pink in color. It contains serous exudate, erythrocytes, leukocytes, cervical mucus and microorganisms. This stage continues until around the tenth day after delivery. Lochia serosa which persists to some weeks after birth can indicate late postpartum hemorrhaging, and should be reported to a physician.
- Lochia alba (or purulenta) is the name for lochia once it has turned whitish or yellowish-white. It typically lasts from the second through the third to sixth weeks after delivery. It contains fewer red blood cells and is mainly made up of leukocytes, epithelial cells, cholesterol, fat, mucus and microorganisms. Continuation beyond a few weeks can indicate a genital lesion, which should be reported to a physician.
Complications
In general, lochia has an odor similar to that of normal menstrual fluid. Any offensive odor or change to a greenish color indicates contamination by organisms such as chlamydia or staph saprophyticus.{{cite web |title=What Is Lochia |website=Elite Doula |url=http://elitedoula.com/blog/39/what-is-lochia}}
Lochia that is retained within the uterus is known as lochiostasis{{cite web |title=lochioschesis - definition of lochioschesis in the Medical dictionary - by the Free Online Medical Dictionary, Thesaurus and Encyclopedia. |url=http://medical-dictionary.thefreedictionary.com/lochioschesis}} or lochioschesis, and can result in lochiometra{{cite web |title=lochiometra - definition of lochiometra at the Free Dictionary by Farlex |url=http://medical-dictionary.thefreedictionary.com/lochiometra}} (distention of the uterus - pushing it out of shape). Lochiorrhea describes an excessive flow of lochia and can indicate infection.{{cite web |last=Shevtsova |first=Maria |date= |title=Postpartum Bleeding – The Healing Wound |website=Mother How |url=http://motherhow.com/postpartum-bleeding/ |quote=Also, a profuse lochia discharge three weeks after childbirth can be a {{sic|sing|nolink=y|hide=y|expected=sign}} of lochiorrhea.
