bloating from nondairy foods triggered by lactose intolerance ?

so, i’ve noticed that whenever i eat dairy foods, my stomach is way more sensitive to reacting to all foods. even like days after consuming dairy, i’ll get bloated from sugary or fried foods even if they are totally nondairy. did the lactose make my stomach sensitive or something? has this ever happened to y’all due to lactose intolerance or is this totally something different?
