How to repeatedly check if statements?

I've written the following code and am having trouble with two if statements (lines 9-14 and lines 16-21). Once hungerValue.Value == (either 50 or 20), the msg.Text does not appear anymore during that play-test.

I need to know how to have the code always be checking the hungerValue.Value, even after the statement has fired.

local hungerArray = {"I'm getting hungry.", "I'm nearly starving."}
local msg = Instance.new("Message", game.Workspace)

while wait(hungerDecrease) do
    if hungerValue.Value - 1 >= 0 then
        hungerValue.Value = hungerValue.Value - 1
    end

    if 
        hungerValue.Value == 50 then
        msg.Text = hungerArray[1]
        wait(5)
        msg:Remove()
    end

    if
        hungerValue.Value == 20 then
        msg.Text = hungerArray[2]
        wait(5)
        msg:Remove()
    end
end
