It Might Be From An Injury

Left-handed people are more likely to have a larger left arm than right arm, and there is no clear reason why this is the case. Some believe that left-handed people are born with a bigger left arm because it helps them with coordination.

Another theory suggests that during development, the left hemisphere of the brain controls the right side of the body more than the other way around. Whatever the cause may be, left-handed people are more likely to have a larger left arm than right arm.

If you’re wondering why your left arm is bigger than your right, there isn’t an easy answer – but there is research being done to find out more about it! If you notice that your left arm is bigger than your right, don’t worry – it’s not something that will go away on its own but can be treated with therapy or surgery if needed.

If you think that your left arm might be bigger than your right due to an injury, consult with a doctor to see if there is anything that can be done to treat it. In some cases, surgery may be able to correct the size difference between arms and sometimes this involves breaking the bones in one or both arms so they become equal in size again.

Therapy can also help change how use muscles in one or both arms, which often results in a smaller size difference between arms over time. No matter what the cause may be, if you notice that your left arm is bigger than your right – whether from an injury or birth defect – consult with a doctor as soon as possible so that any necessary treatment can begin immediately.

Heredity And Genetics

Genetics and heredity play a role in determining how your arms will look and size. If you have larger arms, it may be because of genetics. You can’t change the fact that you were born with big arms, but you can take steps to keep them healthy by following a healthy diet and exercising regularly.

If genetics is responsible for your arm size, then there’s nothing that you can do to change that. However, if your arms are smaller than average, there are things that you can do to make them look bigger, like wearing clothes that fit well or using body enlargement products. Trying different exercises and lifting weights may also help increase the size of your arms.

Eating more fruits and vegetables may also help since they contain vitamins and minerals that help boost arm size. Drinking plenty of water is also important since it helps flush out toxins from the body which could contribute to arm size issues. Avoid eating foods that contain high levels of sugar as this will lead to weight gain around the arms and other areas of the body as well as increased risk for heart disease and other health problems.

Finally, make sure to get enough sleep every night so that your muscles don’t shrink during the day due to lack of rest.

The Role Of Hormones In Arm Size

Hormones play a significant role in determining arm size. There are two primary hormones that control arm size- estrogen and testosterone. Estrogen is responsible for the growth of breasts, while testosterone affects muscle and fat accumulation in the body.

Each person’s hormone levels are different, so some people may have larger arms than others due to their hormone levels. Some activities like weightlifting can increase your testosterone levels, which can lead to increased arm size. Certain medications can also cause an increase in arm size- specifically those that block estrogen receptors.

If you want smaller arms, you will need to reduce your estrogen levels through diet or supplements. You can also laser treatments that break down excess skin around the arms, which decreases arm size over time. In some cases surgery may be necessary to reduce arm size due to genetic abnormalities or tumors that affect the hormones responsible for arm growth.

Very less people has non dominant arm bigger.

Weightlifting And Arm Size

One common reason why one arm may be bigger than the other is because of weightlifting. When you lift weights, the muscles in your left arm are working harder than those in your right arm.

This can cause your left arm to become larger than your right arm, even if you don’t have any genetic abnormalities. To prevent this from happening, it’s important to focus on your right arm when lifting weights and avoid using too much pressure on your left arm.

You can also try training your left arm separately by doing things like weighted push-ups or tricep extensions. Also, make sure that you’re drinking enough water and eating a balanced diet to help support your muscle growth. If you do experience an increase in arm size as a result of weightlifting, don’t worry – it’s not something that will stay permanent.

In most cases, the size difference will eventually disappear over time as your arms return to their normal size and strength levels. However, if you notice that your arms are continuing to grow despite following these guidelines, then speak with a doctor about what might be causing the increase in size.


This could be a sign of health problems such as arthritis, genetics, or even a stroke. Seek medical help if it persists or worsens.
