Dr. Zachary Spiritsos shares expert insights on the connections between digestive issues and conditions like POTS, MCAS, and EDS. He explains how these overlapping conditions present with distinct symptom patterns that can help patients better understand their complex health challenges.

• Neurogastroenterologists are “electricians, not plumbers” – focusing on nervous system connections to digestive issues
• POTS typically presents with racing heart upon standing, brain fog, blood pooling, and various GI symptoms
• MCAS features “twitchy” mast cells that react to everything from temperature changes to emotions
• Primary MCAS symptoms include skin manifestations (itching, rashes), ENT issues, and GI symptoms like unexplained heartburn
• EDS often shows up through joint hypermobility, subluxations, and can be assessed using the Beighton score
• These conditions frequently overlap, requiring thorough questioning to properly identify and treat

Spiritsos
,

Please

help

me

in

welcoming

Dr

Zach

Spiritos
.

Dr

Zach

Spiritos
,

talk

to

us

a

little

bit

about

what

you

see

in

symptoms

with

your

hypermobile

EDS

people

and

your

POTS

people

and

the

MCAS

people
.

What

are

the

things

that

you

see

most

in

those

patients
?

Because

I

bet

you
,

if

we

could

sit

down

and

identify
,

okay
,

these

are

some

of

our

symptoms

too
.

Here's

maybe

some

ways

we

can

address

that
.

What

do

you

typically

see

in

those

three

subsets

of

patients
?

POTS Symptoms and GI Connections

Speaker 2
1:30

Yeah
,

so

they

land

in

my

lap
.

So

I'm

a

neurogastroenterologist
,

so

I

stole

this

from

this

amazingly

smart

doctor
,

dr

Brandler
,

who's

a

neurogastroenterologist

up

in

Seattle
,

and

it's

we

are

electricians
,

not

plumbers
,

okay
.

And

so

when

patients

come

to

me

they

have

GI

symptoms
,

but

then

they

start

talking

about

other

things

that

don't

necessarily

fit

into

IBS
.

So

I

initially
,

when

I

first

graduated

and

I

was

in

practice
,

I

took

on

a

lot

of

IBS

patients
.

I

just

happened

to

love

taking

care

of

that

patient

population
.

But

then

someone

would

say

you

don't

have

IBS
.

But

all

of

a

sudden

when

I

get

up
,

my

heart

just

races
,

like

that's

not

IBS
.

I

think

an

antiquated

view

of

that

is

like
,

oh
,

you're

stressed

and

stress

causes

anxiety

and

stress

causes

palpitations
.

But

this

is

different
.

So

in

POTS

the

hallmark

feature

is

standing

up

and

just

feeling

like

your

heart

is

racing
.

Okay
,

and

with

that

I

would

say

that

brain

fog

is

a

really

big

symptom

there
.

And

then
,

kind

of

secondarily
,

some

people

get

a

lot

of

blood

pooling

in

their

feet
,

like

their

feet

get

swollen
.

But

yeah
,

certainly

the

standing

tachycardia

or

the

heart

racing

from

going

or

sitting

to

a

standing

position

is

the

hallmark

features

of

postural

orthostatic

tachycardia

syndrome
,

but

they

also

may

have

a

lot

of

GI

symptoms

getting

full

early
,

tons

of

bloating
,

loose

stools
,

conversely

constipation
.

So

the

POTS

GI

system

doesn't

really

follow

any

specific

rulebook
,

unfortunately
.

Speaker 2
3:03

Yeah
,

okay
,

so

mass

cell

activation

syndrome

is

and

of

course

this

can

be

linked

with

MCAS: Beyond Skin Manifestations

Speaker 2
3:11

POTS

too
.

So

when

I'm

talking

to

one

of

these

patients

I'm

asking

all

these

questions
,

I'm

screening

for

every

one

of

these

things

to

see

if

we

can

kind

of

piece

this

together
.

But

the

hallmark

feature

of

mass

cell

activation

syndrome

is

probably

skin

manifestations
,

so

itching
,

rashes
,

secondarily

kind

of

ears
,

nose

and

throat

issues
,

rhinorrhea
,

eyes

watering

for
,

like
,

no

good

reason
.

And

then

GI

symptoms

are

kind

of

probably

coming

third

there

and

that's

bloating
,

diarrhea
,

diarrhea
,

lots

of

heartburn

and

someone

who
,

like

shouldn't

get

heart
.

You

know

heartburn

traditionally

affects

people

who

are
,

you

know
,

a

little

bit

older
,

you

know

have

their

bmis
,

or

are

you

probably

closer

to

30
,

like

we

see

these

young

women

who

are

22
,

23
,

with

rip-roaring

heartburn
.

I'm

like

that

ain't

cured
,

it

just

doesn't

make

any

sense

and

that's

m
.

So

that's

where
.

Speaker 2
4:06

So
,

just

like

one

of

the
,

without

getting

too

into

the

nitty

gritty

of

the

pathophysiology

of

MCAS
,

but

these

mast

cells

are

just

very

twitchy

right
.

They're

intended

to

be

selectively

defensive

against

certain

pathogens

that

our

body

doesn't

like
.

Like

you

know
,

mold

If

anybody's

in

North

Carolina

like

me

just

the

pollen

is

insane
.

So

mast

cells

are

supposed

to

be

acting

up

now
,

but

these

mast

cells

become

twitchy

and

react

to

virtually

everything
,

from

temperature

changes

to

emotional

changes
,

to

poor

sleep
,

to

medications
.

It's

really

wild
,

and

one

of

the

chemicals

that

it

releases

and

it

releases

hundreds

of

chemicals

is

histamine
,

and

histamine

plays

a

big

role

in

creating

acid

secretion

from

the

stomach

which

could

lead

to

heartburn

symptoms
.

Speaker 2
4:51

But

for

all

intents

and

purposes
,

patients

don't

behave

like

traditional

gastroesophageal

reflux

patients
.

They

don't

respond

to

proton

pump

inhibitors

and

they

have

no

darn

reason

to

have

reflux

to

begin

with
.

They

don't

have

a

big

hiatal

hernia
,

which

is

a

traditional

risk

factor

for

heart

reflux
,

or

they're

not
.

You

know

they're

not
.

They're

not

overweight
,

and

so

that's

where

you

have

to

start
.

You

know

this

doesn't

quite

make

sense
,

okay
,

and

you

said

EDS
.

Speaker 1
5:17

EDS
,

this

is

a

big

one

for

us
,

okay

EDS Symptoms and Joint Mobility

Speaker 1
5:19

,

I
?

Speaker 2
5:19

have

a

lot

of

questions

for

this

one
.

Speaker 2
5:21

So

again

I

have

a

lot

of

questions

for

this

one
.

So

again
,

I'm

a

GI

doctor

so

I

deal

with

a

lot

of

the

GI

manifestations
.

But

I

certainly

screen

for

all

of

you

know
,

all

my

patients

who

I

you

know
,

who

have

MCAS
,

who

have

POTS
,

for

EDS
,

specific

symptoms

and

the

Baten

score

is

really

nice

Testing

certain

joint

mobile

hyperflexibility
.

You

know
,

being

able

to

put

both

palms

on

the

floor

with

extended

knees
.

You

know
,

are

you

able

to

bend

your

pinky

back

beyond

a

certain

angle
?

You'd

be

able

to

bend

your

thumb

beyond

a

certain

angle

and

you

can

look

up

the

bite

and

score

and

kind

of

assess

for

yourself
.

Speaker 2
5:51

But

you

know
,

did

you

have

kind

of

weird

random

joint

subluxations

as

a

kid
?

Did

your

knee

just

pop

out

of

joint
,

like

that's

not

supposed

to

happen
,

right
,

and

they're

like

oh

yeah
,

we

put

a

brace

on

it

and

kind

of

said

that

was

fine
.

I

was

like

that's

not

fine
,

like

that

doesn't

happen
.

So

you

have

to

always

ask

why
,

exactly

like

if

you're

an

exchange
,

like

if

you're

sean

white

and

doing
,

you

know
,

kick

flips

on

the
,

uh
,

on

the
,

on

the

half

pipe
,

fine
,

like

that's
,

that's

reasonable
.

But

just

like
,

yeah
,

I

was

playing

kickball

and

my

knee

just

popped

out

of

place
,

like

that's

not

a

thing
,

right
?

So

in

a
,

in

a

nutshell
,

like

a

very

condensed
,

oversimplified

way

of

kind

of
,

I

think
,

compartmentalizing

those

conditions
.

So

it's

really

important
,

you

know
,

to

really

do

a

thorough

review

of

systems

and

ask

all

the

questions

so

you

can

really

understand

why

something

happened
