Explanation

Lupus is a disease that can affect many parts of the body, including the heart and thyroid. Sometimes, people with lupus may also have hypothyroidism, which is when the thyroid doesn't make enough hormones. This can lead to weight gain because the thyroid helps control how fast the body uses energy.

How It Affects the Heart

Heart Health: Both lupus and hypothyroidism can make the heart work harder.
Weight Gain: If the thyroid is not working well, it can slow down the body's metabolism, leading to weight gain.

What to Watch For

If you have lupus and notice rapid weight gain, it's important to speak to your doctor.
They may check your thyroid to see if it's working properly.

If you're experiencing concerning symptoms, you can start by taking a free symptom checker test to help identify potential causes. However, if you have concerns about your health, it's always best to talk to a healthcare professional for proper diagnosis and treatment.
