Working as a Delivery Rider on Hemodialysis: Protecting Your AV Fistula, Preventing Post-Dialysis Dizziness, Managing Thirst in the Heat, and Eating Enough Protein

From a kidney patient group: I am on dialysis but still ride deliveries every day. What should I watch out for?

Direct answer: still working while on dialysis is something to be genuinely proud of, and it can continue safely if you protect your fistula, do not force yourself to ride before your body has recovered,
control salt and fluid even in hot weather, and never let work replace a dialysis session.

One member of a kidney patient group wrote: “I’m a dialysis patient who can still ride deliveries a little, earning a bit over a thousand baht a day. I wake up and admire my body for fighting every day. Let’s keep going together, dialysis friends.”
That spirit helps other patients a lot. This article summarizes the evidence so outdoor work and dialysis can go together for the long run.

1. Ground rules for protecting your fistula or graft while riding and working

Direct answer: a fistula carries fast blood flow from an artery straight into a vein, so anything that presses on or squeezes that arm for long slows the flow and raises clot risk. Protection is simple but has to happen every day.

Do and avoid

• Carrying a delivery bag or hanging heavy bags on the fistula arm — use a rear box or the other arm
• Watches, bracelets, rubber bands or tight sun sleeves on that arm
• Blood pressure readings, blood draws or drips on the fistula arm
• Sleeping on that arm or keeping it tightly bent for long periods
• Scratching or picking needle-site scabs

• Wear a thin, loose sun sleeve to prevent scratches and sunburn
• On long rides, stop, relax your grip on the handlebar, and move fingers and wrist regularly
• Wash the fistula arm with soap and clean water daily and before every session
• Look at, feel and listen to your fistula every morning and after work

Thrill versus bruit

The thrill is a purring vibration you feel with your fingers; the bruit is a continuous whooshing sound you hear with your ear or a stethoscope.
The 2019 KDOQI vascular access guideline (Lok 2020)
encourages patients to check their own access by look, feel and listen every day, and supports prompt treatment of a clotted access, because the sooner it is treated the better the chance of reopening it.

If you still have a neck or chest catheter

Catheters carry a higher risk of bloodstream infection than an arm fistula. Keep the dressing clean and dry at all times, protect it from sweat and rain, wear a rain cover while riding,
do not remove the dressing yourself, and go to hospital immediately for fever or chills, especially during or after dialysis.

2. After dialysis and before riding: how long recovery takes, and why never to skip sessions

Direct answer: recovery time after dialysis varies widely between people. Ride when you can stand without dizziness and feel fully alert, not by a set clock, and skipping or shortening sessions for work clearly raises the risk of death.

Why dizziness is common after dialysis

Intradialytic hypotension happens during treatment while fluid is being removed; afterward, many people still have a drop in blood pressure on standing, fatigue or cramps.
The DOPPS study of 6,040 patients (Rayner 2014)
found that 32% recovered within 2 hours, 41% took 2–6 hours, 17% took 7–12 hours and 10% needed more than 12 hours.
Days with more fluid removed usually take longer, and people in full-time employment tended to recover faster.
A meta-analysis (Dou 2023)
found post-dialysis fatigue in 61.0%, so it is common and worth planning work around rather than pushing through.

Self-check before riding after dialysis

• You can stand without dizziness, blurred vision or a racing heart
• You have eaten, and if you have diabetes, your blood sugar is not low
• You feel alert, not heavy-eyed
• Needle sites have fully stopped bleeding
• If you are not ready, rest longer or get a lift; on dialysis days, take only short shifts or none

If you are often dizzy after dialysis, tell your kidney team, because your dry weight, fluid removal rate or blood pressure medicine timing on dialysis days may need review. Do not stop or adjust blood pressure medicine on your own.

Never skip or shorten a session for work

DOPPS data (Saran 2003)
linked skipping at least one session a month with higher mortality (RR 1.30) and more hospital admissions.
Data on 32,065 US patients (Foley 2011)
also showed that the day after the long 2-day gap, such as after a weekend, had a mortality rate of 22.1 versus 18.0 per 100 person-years.
The long gap is when salt and fluid control matter most. If your work schedule clashes with dialysis, ask your team to change your slot rather than skipping or coming off early.

3. Managing thirst while working in the sun: start with salt, not just water

Direct answer: salt is the main driver of thirst. Cut salt and thirst falls on its own; the fluid you drink still has to stay within your team’s limit even in the heat, so cool your body down instead of drinking to compensate.

How much water salt makes you drink

A review on reducing salt in hemodialysis (Lindley 2009)
explains that people who no longer pass urine need about 1 liter of water for every 8 grams of salt eaten. With salt under 6 grams a day and drinking only when thirsty, weight gain should stay at about 0.8 kg a day or less.
Trying to restrict water while still eating salty food usually fails.

A study of 34,107 hemodialysis patients (Kalantar-Zadeh 2009)
found that gaining 4.0 kg or more between sessions was associated with a higher risk of cardiovascular death (HR 1.25) compared with gaining 1.5–2.0 kg.

Heat is more dangerous for dialysis patients

A study of 7,445 US hemodialysis patients (Remigio 2019)
found extreme heat days were linked to more same-day hospital admissions (RR 1.27) and deaths (RR 1.31).
Heat widens blood vessels, makes blood pressure drop more easily and increases the urge to drink, so dialysis patients need a plan for avoiding heat.

Tips for a dry mouth on delivery runs

• Avoid salty food such as instant noodles, soups, dipping sauces, sausages, meatballs, salted fish and heavily seasoned boxed meals
• Split your daily fluid allowance into small bottles, use small cups and sip slowly
• Suck small ice chips, and count the ice as fluid
• Rinse your mouth with cold water, chew sugar-free gum or suck sour sugar-free sweets, use lip balm
• Take jobs in cooler hours, rest in the shade, use a cold towel on the neck, face and wrists, and wear a ventilated cap or helmet
• Weigh yourself every morning; if weight is rising faster than your team’s target, cut salt and fluid straight away
• If you have diabetes, keep blood sugar controlled, because high sugar causes intense thirst

• Sports drinks, coconut water and fruit juice — high in sodium or potassium
• Gulping large glasses of cold water because it is hot
• Assuming heavy sweating means you can drink freely — sweat loss is usually smaller than it feels; if your dry weight shifts in the hot season, let your team adjust it

4. Protein and energy for dialysis patients doing physical work

Direct answer: people on hemodialysis need more protein than people with kidney disease who are not yet on dialysis, because every session removes amino acids, and riders working all day need enough energy so the body does not break down muscle.

The 2020 KDOQI nutrition guideline (Ikizler 2020)
recommends about 1.0–1.2 g of protein per kilogram of body weight per day for stable hemodialysis patients, with energy of about 25–35 kcal per kilogram per day depending on activity.
A 60 kg person therefore needs about 60–72 g of protein a day.

• Egg whites, fish and skinless chicken are good proteins with less phosphorus than processed meat
• Take phosphate binders with meals as prescribed, and carry them when eating out
• Plan meals around delivery runs, do not skip meals, and carry protein snacks your team recommends
• Ask the dialysis unit dietitian to plan menus around your own potassium and phosphorus results

• Processed food and dark colas — they contain highly absorbable phosphate additives
• Large amounts of high-potassium fruit such as durian, banana and orange if your potassium runs high

If your work schedule cannot fit in-center hemodialysis, peritoneal dialysis or a kidney transplant may be options worth discussing with your doctor. See

5. Comparison table: delivery-work risks and how to prevent them on hemodialysis

Direct answer: most delivery-work risks for dialysis patients can be prevented by keeping loads off the fistula arm, planning work around dialysis, controlling salt and avoiding heat.

Frequently asked questions (FAQ)

The questions working dialysis patients ask most often

Can people on hemodialysis work as delivery riders or do physical work?

Many can, if they are stable and their kidney team agrees. Work supports both income and morale, and in the DOPPS study people in full-time employment tended to recover faster after dialysis. The key conditions are never skipping or shortening sessions for work, protecting the fistula arm, not riding while dizzy after dialysis, controlling fluid and salt even in hot weather, and eating enough protein. If you have heart disease, have fainted before, or often have low blood sugar, ask your doctor whether riding is safe.

How do I protect my fistula arm from clotting when riding or carrying deliveries?

Do not let anything press on or squeeze that arm. Do not carry bags or hang heavy shopping on the fistula arm, do not wear a watch, bracelet or tight sleeve on it, do not allow blood pressure readings or blood draws on it, and do not sleep on it. Carry loads with the other arm or use a rear delivery box instead of a shoulder bag, and take breaks to relax your grip and move your hand on long rides. If you have a neck or chest dialysis catheter, keep the dressing dry at all times and protect it from sweat and rain.

How do I feel the thrill of my fistula, how is it different from the bruit, and when should I go to hospital?

The thrill is a purring vibration you feel when you rest your fingers on the fistula, while the bruit is the continuous whooshing sound you hear when you put your ear or a stethoscope on it. The KDOQI guideline encourages patients to look at, feel and listen to their access every day. If the thrill disappears, becomes much weaker, or turns into a pulse-like throb instead of a continuous buzz, contact your dialysis unit or go to hospital the same day, because a clotted access is more likely to be reopened when treated early.

How many hours should I rest after dialysis before riding or going to work?

There is no fixed number. In the DOPPS study, 32 percent of patients recovered within 2 hours, 41 percent took 2 to 6 hours, and about a quarter needed more than 6 hours, and days with more fluid removed usually take longer. Ride only when you can stand up without dizziness or blurred vision, have eaten, and feel fully alert. If you are still tired or lightheaded, rest longer or get a lift. If you are often dizzy after dialysis, tell your kidney team so they can review your dry weight and blood pressure medicine timing.

Working in the sun makes my mouth very dry. How do I stay within my fluid limit?

Salt is the main driver of thirst. People who no longer pass urine need about 1 liter of water for every 8 grams of salt they eat, and with salt under 6 grams a day and drinking only when thirsty, weight gain should stay at about 0.8 kilograms a day or less. Cut salty food such as instant noodles, soups, dipping sauces and processed meat. Use small cups and sip slowly, suck small ice chips and count them as fluid, rinse your mouth, chew sugar-free gum, ride in cooler hours, rest in the shade, and weigh yourself every day.

I sweat a lot in the heat. Can I drink sports drinks or coconut water?

Not without asking your kidney team. Sports drinks contain sodium, which increases thirst, and potassium, while coconut water and fruit juice are high in potassium, which in dialysis patients can cause muscle weakness and dangerous heart rhythms. Daytime sweat loss is usually smaller than it feels and does not mean you can drink freely to replace it. Cool the body instead, with a cold towel on the neck and face, a ventilated helmet or cap, and shade breaks. If your weight changes a lot in the hot season, ask your team about adjusting your dry weight.

How much protein does a dialysis patient doing physical work need, and which foods are best?

The 2020 KDOQI guideline recommends about 1.0 to 1.2 grams of protein per kilogram of body weight per day for stable hemodialysis patients, so a 60 kilogram person needs about 60 to 72 grams a day, because each session removes amino acids. Good sources are egg whites, fish and skinless chicken, which carry less phosphorus than processed meat. Take phosphate binders with meals as prescribed, and do not skip meals while working, because too little energy makes the body break down muscle.

Which symptoms mean I should go to hospital immediately?

Go to hospital or call emergency services immediately if a needle site keeps bleeding after 10 minutes of firm pressure, you are breathless or cannot lie flat, have chest pain, palpitations or an irregular heartbeat, severe muscle weakness, fainting, or become very hot, confused or stop sweating while working in the sun. Contact your dialysis unit the same day if the fistula has no thrill, the arm is swollen, red, hot or has pus, you have fever or chills, or the hand on the fistula side is cold, pale, numb and painful.

Scientific mechanism (brief)

Summary by Asst. Prof. Dr. Norawit Raatpiboon:
a fistula connects an artery directly to a vein, so blood flows at several hundred milliliters a minute, thickening the vein wall and producing the thrill.
Prolonged external pressure or low blood pressure slows that flow and creates turbulence, and together with narrowing from neointimal hyperplasia this leads to clotting.
During dialysis, fluid is removed from the bloodstream faster than fluid from the tissues can refill it, so blood volume falls temporarily; heat dilates skin blood vessels and worsens the pressure drop on standing.
Salt raises blood osmolality and triggers the brain’s thirst center; people who no longer pass urine cannot excrete that water and salt, so what they drink accumulates as weight gain and strains the heart.
Each dialysis session also removes amino acids along with waste, and chronic inflammation adds to protein breakdown, which is why protein needs are higher than before dialysis.
