Blood Clot vs Miscarriage: Difference and Comparison

Blood clots and miscarriages can be indistinguishable for some, although they are very different. Blood clots are significantly different from miscarriages because they are smaller.

Even the causes of each can be distinct, but so can the associated concerns. Yet, people tend to misunderstand them as similar. 

Key Takeaways

  1. Blood clots occur when blood thickens and forms a solid mass, while miscarriages result from losing a pregnancy before the 20th week.
  2. Blood clots can be life-threatening if they travel to the lungs, heart, or brain, but miscarriages do not risk the mother’s life.
  3. Treatment for blood clots involves anticoagulant medications or surgery, while miscarriages may require medical or surgical intervention to prevent complications.

Blood Clot vs Miscarriage

The difference between blood clots and miscarriage is that blood clot is thick and sticky clumps of dried blood. Meanwhile, miscarriage is a disrupted pregnancy where the fetus is incompetent to survive before birth. Secondly, every woman suffers from blood clots throughout her period. Miscarriages, on the other hand, occur in only 20% of women. Thirdly, blood clots can be caused by an unhealthy lifestyle, such as cervical diseases, hormonal imbalances, uterine fibroids, and so on. Miscarriages, on the other hand, might be caused by anomalies, toxic drug ingestion, uterine anatomical features, and so on. Fourthly, blood clots appear red, while miscarriage seems to be greyish tissue along with red blood clots. Finally, an ultrasound scan shows blood clots have black spots, whereas a miscarriage ultrasound shows white areas.

Miscarriage is a disrupted pregnancy where the fetus can’t survive before birth. Only 20% of women experience miscarriages.

As for the reason for the occurrence, it occurs due to abnormalities, intake of a toxic substance, structural features of the uterus, etc. Moreover, it appears to be greyish tissue along with red blood clots, although an ultrasound scan shows white areas.

What is a Blood Clot?

Blood clots are defined as thick and sticky clumps of dried blood. Many women experience it during their periods. Some women may have experienced it, while some may have not. However, it is somewhat familiar for women in their periods. 

Although, it may happen in different places as well. But usually, a lot of women see blood clots during their period.

Many factors result in the formation of blood clots, such as a sedentary lifestyle, hormonal imbalance, uterine cervix disorder, intrauterine devices, etc. 

Additionally, if factors or reasons for the formation are briefly explained, a sedentary lifestyle is one of the primary reasons. A sedentary lifestyle impacts a woman’s health as blood gets retained due to low physical activity; thereby, clots are formed. 

Another reason is uterine cervix disorder, which leads to blood clots, forming and may develop due to a sinful lifestyle, genetics, abortion, etc.

Also, hormonal imbalance can lead to developing blood clots as increased levels of hormones result in endometrial growth. 

Besides these, there can be other reasons, such as the presence of intrauterine devices, polyps in the uterus, uterine fibroids, low haemoglobin, etc.

Moreover, it appears red, although an ultrasound scan shows blood clots have black areas.

What is Miscarriage?

Miscarriage is defined as disrupted pregnancy where the fetus can’t survive before birth and is ejected from the uterus before developing. Usually, it happens before the 20th gestational week. 

However, miscarriages are very common, as 20% of the women have experienced a miscarriage when they knew they were pregnant. Besides, it is also frequent in women who didn’t detect their pregnancy, as early miscarriages are also common. 

And one of the statistics shows that 80% of miscarriages happen before the 20th gestational week. Additionally, factors affecting and reasons behind miscarriages have a broad spectrum, from genetics to lifestyles. 

One of the reasons for the occurrence of miscarriage is abnormalities in the uterus, intake of toxic substances, structural features of the uterus, etc. Generally, 95% of genetic and embryonic abnormalities result in miscarriages. 

Although, miscarriage happens at an early stage, before the 20th gestation week. Yet, it can also occur due to arrhythmia after the development of the embryo in the uterus. 

How can it be detected? It happens along with acute abdominal pain and bleeding—additionally, unbearable cramps in the abdomen to the legs and thighs. Even severe back pain and heavy bleeding can be experienced. 

With the brown discharge, starts, and it is followed by bright red or pink shot along with blood clots for 2 to 3 days.

After that, small kidney-shaped grey tissue discharges, and can also discharge as a ball-shaped sac if the pregnancy is beyond 6-8 weeks.
