Blood Loss Recovery: The Complete Guide

Blood loss in females can happen for a variety of different reasons. Heavy prolonged menstrual bleeding due to fibroids results in chronic blood loss and anemia. Today we are going to talk about how to recover after blood loss and how to treat the underlying cause of chronic blood loss.

Dr. E. M. Braunstein, a hematologist from the Johns Hopkins School of Medicine, reported that symptoms of blood loss vary depending on the speed and amount of blood loss. Blood loss is normally categorized as acute or chronic. Acute blood loss is losing blood at a rapid rate and chronic blood loss is losing blood over a longer period of time.

What Can Cause Significant Blood Loss?

Several things can cause significant blood loss including the obvious: an accident, internal injury, or complications from surgery. Then there are the subtle causes of significant blood loss, such as prolonged heavy menstrual bleeding from endometriosis, adenomyosis, or uterine fibroids. Many women suffer each month from these issues but do not realize that they are losing a dangerous amount of blood, as the effects happen gradually and progressively over time. They often do not realize that the blood loss they are experiencing is abnormal and that they should seek medical help. Their periods may have always been heavy so to them it seems normal.

How Much Blood Loss Is Too Much?

How much blood can you lose before your health is at risk? The amount of blood loss a person can endure depends on their age, size, and general health. Men typically have more blood than women so their threshold is a bit higher. Children have a much lower threshold because they do not have as much blood, to begin with.

Most adults can lose around 14 % of their total blood supply without feeling negative effects however, once that 14% mark is surpassed, individuals will begin to experience adverse side effects.

How Many Pints Of Blood Can You Lose?

Most average size adults have between 9 and 12 pints of blood in their body. The amount of blood loss a person can safely sustain will depend on how much they weigh, their age, gender, and other factors. On average adults can safely lose between 1.26-1.68 pints of blood without adverse effects. Exsanguination (losing enough blood to cause death) can occur if an individual loses more than half their blood supply.

Signs of Excessive Blood Loss

If you are experiencing significant blood loss, you will begin to show various signs as your condition worsens. It is important to recognize these signs and symptoms of blood loss and get emergency care as soon as possible. The higher the percentage of blood loss, the more dangerous a threat to your health becomes.

  • 15-30% blood loss can cause nausea, a decrease in urine output, a decrease in blood pressure, and an increase in heart and respiratory rates. It can also make you feel weak, tired, anxious, or ill at ease. As your body tries to compensate for the loss of blood, the blood vessels in your extremities will constrict causing the skin to become pale.
  • 30-40% blood loss is very dangerous, blood pressure will drop, and the heart rate will increase. Some other signs of blood loss that may be experienced are disorientation (obvious confusion) and the patient’s breathing may become more rapid and shallow. The body will be struggling to maintain adequate blood pressure and circulation, which may bring about the loss of consciousness.
  • 40-50% blood loss – the most dangerous of all the blood loss symptoms occurs when the heart cannot maintain blood pressure or circulation. Organ failure becomes imminent, followed by a coma and, most likely, death unless emergency medical intervention takes place.

Chronic Blood Loss in Women

Many women experience a significant loss of blood each month during their menstrual cycle and can also bleed in between their periods. This is categorized as chronic blood loss and is normally caused by an underlying condition, such as adenomyosis, endometriosis, polyps, or uterine fibroids. Many women who suffer from chronic blood loss often have clinical symptoms of anemia.

Anemia from Blood Loss

Anemia is a lack of red blood cells that occurs when the body is losing red blood cells faster than it can replace them. Women with anemia bruise very easily, are often chronically fatigued, can have memory issues such called “brain fog”, feel faint or dizzy, experience migraine-like headaches, experience shortness of breath, rapid heart rate (palpitations), chest pain, cold feet or hands, or develop an unusual condition called pica. Causes the individual to chew or crave non-food items like ice, corn starch, dirt, chalk, and clay.

How Long Does Recovery from Blood Loss Take?

The volume of blood that circulates within a person is dependent on factors such as gender, body mass, and size. Women typically have a lower blood volume than men, but the average human body contains approximately 5 liters of blood.

As a point of reference, when you donate blood they usually draw a pint of blood from you. For an average person, this represents about 10% of their total blood supply. About a third of that pint is made up of red blood cells and the rest is pretty much water. You can replace the water portion fairly easily on the first day by drinking plenty of non-alcoholic fluids.

If we were looking at how long it takes to recover from losing 1 liter of blood, the answer would depend on several factors, such as the individual’s overall health, age, the rate and cause of the blood loss, and whether any medical intervention was necessary.

In general, it can take several weeks to fully recover from losing 1 liter of blood. The first priority in the treatment of blood loss is to stop the bleeding and replace the lost volume of blood. This may involve blood transfusions or intravenous fluids to restore blood volume and oxygen-carrying capacity. Once the blood loss has been stabilized, the body will begin the process of replenishing the lost blood.

If the blood loss is due to a minor injury or blood donation, it can take the body anywhere from a few days to a week to replace the lost blood. However, if the blood loss is due to a severe injury or surgery, it can take several weeks for the body to replace the lost blood.

The red blood cells will take approximately 60 days to replenish. It is important to understand that red blood cells carry oxygen to the vital organs and can affect their performance. Runners are advised not to give blood for at least 2 months before a marathon or a big race as it will affect their performance. Red blood cells will not have the ability to carry oxygen to the muscles needed for the athlete to push themselves the extra distance.

What Can I Do to Recover After Losing Blood?

Acute blood loss requires immediate attention and is a medical emergency. Those experiencing chronic blood loss should be monitored and under a doctor’s care.

If you are beginning to experience some of the milder symptoms associated with blood loss and/or possible anemia, there are things you can do to help your body until you can see your doctor. When you are losing red blood cells faster than your body can produce them, you can eat certain foods to help rebuild your blood supply.

For the Immediate Relief

If you are losing a lot of blood during a heavy period and feeling weak or sick, drink some strong black tea with sugar to provide your body with temporary relief and regain some strength.

This tip is especially helpful to those who feel nauseous and struggle with food intake, sometimes for days. Then, when you are feeling better, you should eat something more substantial (see the list of best foods below) to help your body recover faster.

Unlike during a normal period, a heating pad is not recommended during a very heavy period. On the contrary, if you are losing a lot of blood, use an ice pack while laying down on a flat surface and elevate your feet slightly.

Monitor your blood loss very carefully! If you are changing pads more frequently than every 2-3 hours, more than one pad at a time, have accidents in blood, e.g. soiling clothes, bed linens, have blood gush or flood out or pass clots quarter size or larger you need to tell your doctor about these findings immediately.

Tips to Rebuild Your Blood Supply

  • Drink an additional 32 oz of non-alcoholic liquids in addition to the daily recommended amount of water;
  • Get as much sleep as possible;
  • Make sure your daily menu is full of iron-rich foods, folate, and vitamin B-12.

Recommended Foods

  • Iron-rich foods: The best sources of iron are meat, fish, and seafood. These contain what is called heme iron, which is readily absorbed by the body. Beef or chicken liver is often “prescribed” to women who have experienced blood loss. The recommended amount of liver is 2 oz twice a week for 4 weeks.
  • Iron can also be attained through a diet of leafy green vegetables, nuts, seeds, and whole grains but these are classified as non-heme iron, and our bodies have a hard time breaking down and using this iron, so it only absorbs a fraction of the iron content. We now know that the absorption rate of non-heme iron goes up when consumed with vitamin C. So if eating a spinach salad, you could combine it with a glass of orange juice to get the most out of it.
  • Folate can be found in dark green leafy vegetables, avocados, bread, mangoes, oranges, papayas, pomegranates, green peas, kidney beans, peanuts, and enriched grain products, such as bread, cereal, pasta, and rice.
  • Vitamin B-12 can be found in fortified foods but is naturally found in animal products including beef, animal liver, tuna, salmon, eggs, and dairy products.
  • Vitamin C assists with the absorption of iron can be found in kiwi, strawberries, oranges, lemons, and other citrus fruits and juices, broccoli, peppers, and tomatoes.

How Can I Stop Chronic Blood Loss?

Following healthy eating guidelines and consuming foods suggested to combat anemia will certainly help alleviate some symptoms but will not remedy the cause of the blood loss.

If your blood loss is due to chronic uterine bleeding this is divided into two categories and classified by the PALM-COEIN system. The PALM-COEIN classification defines:

  • bleeding due to a non-structural cause, e.g. bleeding disorder, polycystic ovarian syndrome, thyroid disease, and
  • bleeding due to a structural cause e.g. fibroids, adenomyosis.

In the non-structural group medication is the first-line therapy along with addressing the cause of the bleeding. If that is not enough and the woman is not interested in fertility, she could consider an endometrial ablation.

In the much more common structural group, in which fibroids are #1, addressing the structural cause is the best method of treatment. For fibroids or adenomyosis, Uterine artery (fibroid) embolization (UAE/UFE) is the best treatment method. It has a very high success rate, avoids the risks and long recovery of surgery, allows women to keep their uterus, and even preserves an opportunity to try to get pregnant and have children.

UAE/UFE is much safer than surgery and it addresses all symptoms related to uterine fibroids or adenomyosis, including heavy periods and anemia.

If you are experiencing chronic blood loss, do not suffer in silence anymore. Please call Atlanta Fibroid Center at (770) 953-2600 to make an appointment with one of the nation’s leading UAE/UFE experts Dr. John C. Lipman, or make an appointment online at
