Organ weight is a complex issue. There are many factors - including body weight, height, muscle mass, and race - that cause organ weights to vary widely. Much more data must be collected in order to determine exact ranges for organ weights. In addition, this data must come from different types of people. At this time, such data is not routinely collected.

Organ weights used as a reference must be obtained from forensic autopsies, usually performed on suspicious, sudden, or traumatic death when a dead person's organs are otherwise healthy. However, diseased organs examined during a hospital autopsy should not be used to determine reference levels because the disease can actually affect the weight of an organ. In addition, the number of autopsies performed decreases, which gives researchers fewer opportunities to access and evaluate organ weights.

Although underestimated and minimally researched, organ weights and sizes are still used by health professionals to determine the cause of death and disease, and to guide certain treatments.

The payment

In 2001, French researcher Grandmaison and his co-authors published an article in Forensic Science International Analysis of organ weights from 684 autopsies performed on whites between 1987 and 1991. The power and consistency of this study with other organ weight studies, as well as the lack of research on the subject, make it as good a source as any other organ weight study.

Based on the results of this study, the following mean organ weights and ranges for men and women are:


Average weight in men (grams)

Range in men (grams)

Average weight in women (grams)

Range in women (grams)
















Right lung

Right kidney

To some extent, these values ​​are not generalizable and cannot automatically be applied to all individuals in a population. Although people change very slowly over time, the results of this study are already dated.

Anatomical organ weight: how much do breasts weigh?

In the purest sense, “breasts” or breasts are not an organ in themselves, but a collection of mammary glands and breast tissue fat. Even so, the breasts are so clearly distinguishable from the rest of the body that many surgeons who specialize in breast surgery consider “anatomical organs”.

In an often-cited article titled "Contribution of Breast Volume and Weight to Body Fat Distribution in Women," researchers suggest that (based on their assessment) a pair of female breasts weigh about 3.5 percent of the weight of total body fat. However, the sample size of this study is small and the results are a little out of date.

According to the formula, a woman wearing 40 pounds of total body fat would have breasts that weigh about 1.4 pounds for the couple.

"The breast weight varies a lot," says Dr. Bradford Hsu, a breast surgeon affiliated with Sharp Healthcare in Chula Vista, Calif., "Depending on the age and development of the person, both breasts combined can weigh as little as 100 grams or up to four or five kilograms."

In addition, histological changes in the composition of the breasts can sometimes affect breast weight. "When someone has a lot of fibrocystic diseases," says Dr. Patricia Allenby, a pathologist at Ohio State University, "the chest gets heavier than when it is fatter." It has to do with the density of the tissue - and fat has a very low density. "

However, the effect of fibrocystic, adenomatous, or tumorigenic changes on breast weight is relative. "If you have a small, golf ball-sized tumor in a small breast," says Hsu, "that tumor takes up more of the breast than someone who has a very large breast." In one person, this tumor can make up a third of their breast mass, and in another person, this tumor can make up less than one percent of their breast mass. "

In addition to the disease, diet and exercise is another important factor that affects breast mass. When people lose weight, they tend to do so evenly. For example, if a pear-shaped woman were to lose weight, she would maintain her pear shape, but with less mass. It would be proportionally smaller. Women do not lose more of their weight in any part of their body - such as the breasts - after eating and exercising. Targeted fat reduction or “stain reduction” is unlikely.

A woman who is losing weight will not notice a noticeable decrease in breast size. Her breasts would be adequate for her new weight and in proportion to the rest of her body.everything would just be smaller. In a similar context, as with the breasts, people lose a proportional amount of weight from their buttocks while dieting.

Height, weight, lean body mass and BMI

Research shows that people who are taller, weigh more (have a higher body mass index, or BMI), and have leaner body mass, may have heavier organs. Some of these factors suggest that height correlates best with most organ weights. Larger people have organs that weigh more and are proportionally larger.

Heart weight can be greatly influenced by BMI, with overweight people having heavier hearts.

Interestingly, female thyroid weight has little to do with height, weight, and lean body mass. Instead, female thyroid weight can be most affected by iodine intake. In areas where the vast majority of women are consuming enough iodine in their diet, thyroid weights are usually within a consistent range for all women.

Age and gender also affect organ weight. On average, women have lighter organs than men. In addition, as with lean body mass, organ weights tend to decrease with age. Age-related decreases in organ weight are particularly noticeable in the brain mass. In other words, a person's brain gets smaller as they age, which is a natural process. In this context, the brain mass has nothing to do with intelligence. Having a bigger brain doesn't make anyone smarter.

Results of a study published in 1994, published in The pathologist -and based on more than 8,000 autopsies - suggest the average brain weight in men without brain disease is 1336 grams and the average brain weight in women without brain disease is 1198 grams. The researchers also found that male brain weight decreased by an average of 2.7 grams per year and female brain weight decreased by about 2.2 grams per year. In other words, your brain will get lighter over time.

One physical parameter that has an unclear effect on organ weight is obesity. Obesity is an epidemic in the US and rising rates are undermining the credibility of organ weight benchmarks. Certain pathological sources express organ weight as a percentage of body weight and define a direct and proportional relationship.

Dr. Patricia Allenby, pathologist and director of autopsy services at Ohio State University, points out the error in calculating organ weight based on body weight. "Your organs don't gain as much as your body weight. When a person's body weight doubles, the weight of the organ doesn't double."

The effects of disease

It probably should come as no surprise that the impact of disease or pathology on organ weight varies widely and is complex. Certain diseases cause organs to weigh more and certain diseases cause organs to weigh less.

Chronic alcohol consumption is associated with an increase in the size of the heart (cardiomegaly) and an increase in the size of the liver (hepatomegaly). Ultimately, however, liver weight in alcohol addicts may decrease with the development of cirrhosis. In cirrhosis, healthy liver tissue is replaced by scar tissue.

In an article published in 2016, published in Diabetologia, Campbell-Thompson and co-authors suggest that people with type 1 diabetes experience a significant decrease in pancreatic weight that is noticeable at the onset of the disease. However, people with type 2 diabetes do not experience a decrease in pancreatic weight.

In other words, the results of this study suggest that the pancreas "shrinks" in people with type 1 diabetes, and that shrinkage can be seen when a person is first diagnosed with type 1 diabetes (typically during childhood or adolescence).

As for the brain, cerebral atrophy - seen in conditions such as stroke and dementia - leads to a decrease in brain weight.


There is still a lot to learn about organ weights. Investing in such research is important because the size and weight of the organs are factors used to determine the state of health and cause of death during autopsy. Currently, the reference values ​​used for organ weights are not based on convincing evidence and are not universal.

"Organ weights help us determine if there is an abnormality," says Allenby, "and many diseases are related to changes in size - especially in the heart." The organ weight helps us to confirm or correlate the diseases present ... It helps in the diagnosis. "

Looking to the future, non-invasive imaging modalities such as MRI and CT may prove useful in determining organ weights without the need for an autopsy. In an article published in Investigative Radiology, Jackowski and co-authors found that liver and spleen weights can be estimated using imaging data and volume analysis software.

In fact, the researchers suggest that such imaging may be more accurate than an autopsy in determining liver and spleen weights in the event of constipation (shock), since there are no changes in intrahepatic blood volume during imaging. They also predict more promising results in using CT to determine organ weights - CT is cheaper and easier to use than MRI, and purifying gases and embolized air limits the usefulness of MRI. Embolized air refers to air trapped in the blood vessels of the circulatory system.
