Organomegaly can be a strong predictor of an underlying pathological condition. There are many standard tables available in various texts listing the normal organ weight range, yet there is a lack of a standard table that is accepted globally. The main reason behind this is variation in organ weight due to socioeconomic status, geographical variation, and racial and stature variation among different global populations. The Western population has different stature compared to our population, that is, residents of Uttarakhand, India. Different studies tabulated organ weights in different regions of the world and correlated with different bodily parameters such as sex, race, stature, BMI, etc, which have shown a significant variation. There are different sets of data available that cannot be accepted universally due to regional variation. Most of the studies done in various parts of the world do not specify the condition of the organ, whether it was normal at the time of study or not. The methods of dissection of organs were also not explained in different studies. In this study, a total of eight organs were weighed from 137 autopsies conducted at the mortuary of the All India Institute of Medical Sciences Rishikesh over a period of 1.5 years. It was found that the average brain weighed in males was 1313.2 gm (±127.7 gm) and among females, it was 1218.0 gm (±122.82 gm). The weight of the heart was 310.1 gm (±83.97 gm) in males and 241.2 gm (±71.42 gm) in females. Right and left lungs weighed 499.4 gm (±207.5 gm)/407.5 gm (±128.66 gm) and 459.6 gm (±179.19 gm)/369.4 gm (±144.17 gm) among males and females, respectively. The liver weight was 1477.0 gm (±370.52 gm) in males and 1309.0 gm (±274.18 gm) among females. Spleen weighed 154.0 gm (±74.63 gm) in males and 156.0 gm (±65.0 gm) in females. The right and left kidneys weighed 125.9 gm (±37.92 gm)/108.1 gm (±28.80 gm) and 126.3 gm (±31.26 gm)/106.6 gm (±22.4 gm) among males and females, respectively. In our study, we have done a histological examination to rule out any pathological condition before including the weight of the organs in the study. The present study is to derive a standard organ weight among the inhabitants of Uttarakhand, India, and to look for a variation in organ weight among different studies done in the past in different regions of the world.
