M&M's shows off new chocolate bars with Christina Applegate in the driver's seat of "Bad Passenger."

Christina Applegate is opening up about how multiple sclerosis has taken a toll on her life. The actress, who is known for her roles in “Dead To Me,” “The Sweetest Thing” and “Anchorman,” said having MS “f---ing sucks.” “With the disease of MS, it's never a good day,” she said in an interview with Vanity Fair.

Applegate was diagnosed with MS in August 2021, while she was filming Dead to Me's third season.

The cause of multiple sclerosis is unknown. It's considered an immune mediated disease in which the body's immune system attacks its own tissues. In the case of MS , this immune system malfunction destroys the fatty substance that coats and protects nerve fibers in the brain and spinal cord (myelin).

Going down the stairs, carrying things - you can't do that anymore,” she told GMA. In 2022, Applegate told The New York Times that she first noticed changes in her body a few years ago while shooting the first season of her Netflix show “Dead To Me.”

MS itself is rarely fatal, but complications may arise from severe MS, such as chest or bladder infections, or swallowing difficulties. The average life expectancy for people with MS is around 5 to 10 years lower than average, and this gap appears to be getting smaller all the time.

There is no cure for multiple sclerosis. Treatment typically focuses on speeding recovery from attacks, reducing new radiographic and clinical relapses, slowing the progression of the disease, and managing MS symptoms. Some people have such mild symptoms that no treatment is necessary.

Multiple sclerosis (MS) is a condition that can affect the brain and spinal cord, causing a wide range of potential symptoms, including problems with vision, arm or leg movement, sensation or balance. It's a lifelong condition that can sometimes cause serious disability, although it can occasionally be mild.

Multiple sclerosis signs and symptoms may differ greatly from person to person and over the course of the disease depending on the location of affected nerve fibers. Common symptoms include: Numbness or weakness in one or more limbs that typically occurs on one side of your body at a time. Tingling.

Average life span of 25 to 35 years after the diagnosis of MS is made are often stated. Some of the most common causes of death in MS patients are secondary complications resulting from immobility, chronic urinary tract infections, compromised swallowing and breathing.

We do not know for certain what causes multiple sclerosis. Scientists believe that a combination of factors trigger the disease. Studies support the opinion that MS is caused when people with the right combination of genes are exposed to some trigger in the environment.
