Helping you understand “why your mind suddenly feels foggy” — and gentle ways to improve
Many cancer patients, during or after treatment, notice their mind feels “shrouded in fog”: forgetting what they were about to do, struggling to find words, or having difficulty concentrating.
This phenomenon is medically known as “chemo brain” (Chemo Brain) or “cancer-related cognitive impairment” (Cancer-Related Cognitive Impairment). It is one of the most frequently overlooked yet most impactful symptoms for cancer patients.
It is not simply “being tired” or “getting older” — it is the combined effect of treatment on the brain and nervous system, temporarily disrupting cognitive function.

Helping you maintain more strength to “get through” treatment
During cancer treatment, especially chemotherapy, one of the most common complaints from patients is “no matter how much I sleep, I never feel rested” and “I feel drained all day”.
This is not a matter of “mental weakness” or “not being strong enough” — it is a comprehensive impact of treatment on the body’s energy systems, causing mitochondrial dysfunction, elevated oxidative stress, persistent chronic inflammation, and temporary disruption of energy production mechanisms.
When energy is insufficient, treatment tolerance drops sharply, increasing the likelihood of dose reduction, delays, or inability to complete the full course.

Many cancer patients, after completing chemotherapy, radiotherapy, or surgery, suddenly notice “my hands and feet are starting to feel numb, like pins and needles, or things don’t feel right when I touch them” — sometimes so severe it keeps them awake at night.
This is not simply “getting older” or “nerves wearing out” — it is the gradual emergence of “hidden nerve damage” caused during treatment.
Medically known as “peripheral neuropathy”, it is commonly associated with certain chemotherapy drugs (such as paclitaxel, oxaliplatin, cisplatin, vincristine, etc.) or targeted therapies.

From “Eating Without Benefit” to “Every Bite Supporting Recovery”
After chemotherapy, radiotherapy, or surgery, many people find themselves stuck in a frustrating and confusing cycle:
“I’m doing my best to eat—so why am I still losing weight?”
“Why does it feel like the food I eat isn’t really helping my body?”
This is not simply a matter of poor appetite or insufficient effort.
Cancer-related treatments can have long-lasting effects on the digestive system, metabolism, and gut function, making nutrient absorption far more difficult than before.
When these challenges are properly understood and nutritional support is adjusted with precision and care, each meal can become more meaningful—and the body’s recovery process can gradually regain momentum.

Understanding why “eating more doesn’t always mean absorbing more”—and discovering gentler ways forward

After completing cancer treatment, many patients notice something frustrating:
“I’m really trying to eat, yet my weight keeps dropping.”

This is not a matter of “not trying hard enough.” Rather, long-term effects of treatment on the digestive system and metabolism can make nutrient absorption unusually difficult.
Understanding these common challenges allows you and your care team to intervene earlier—so the nutrients you take in can truly be used by your body.
