You can always -assert- or -count- beforehand:
*************
sysuse auto, clear
forv i=1/5{
forv j=0/1{
di _n in r "rep78==`i' & foreign==`j'"
qui count if rep78==`i' & foreign==`j'
if r(N)>0 tabstat mpg if rep78==`i' & foreign==`j'
if r(N)==0 di in r "Bailing out as no obs" _n(2)
}
}
*************

Many thanks for your response.
I just tried this but the output only shows the display results and
nothing from tabstat. Here is the output:
. foreach i in 0 1 2 3 4 5 {
2. foreach y in male singlet{
3. di "Var =`y' & GA=`i'"
4. capture noisily tabstat bwtg if myga==`i' & intab1==1 &
admit_ic==1 & bwtg<., stat(n mean median p25 p75 min max ) by(`y')
col(stat) f(%9.0g) notot nosep
5. }
6. }
Var =male & GA=0
Var =singlet & GA=0
Var =male & GA=1
Var =singlet & GA=1
Var =male & GA=2
Var =singlet & GA=2
Var =male & GA=3
Var =singlet & GA=3
Var =male & GA=4
Var =singlet & GA=4
Var =male & GA=5
Var =singlet & GA=5
